The BEST of Dinosaurs


Although it has been suggested that most dinosaurs were active during the day, these comparisons have shown that small predatory dinosaurs such as dromaeosaurids, Juravenator , and Megapnosaurus were likely nocturnal.

Large and medium-sized herbivorous and omnivorous dinosaurs such as ceratopsians, sauropodomorphs, hadrosaurids, ornithomimosaurs may have been cathemeral , active during short intervals throughout the day, although the small ornithischian Agilisaurus was inferred to be diurnal.

Based on fossil evidence from dinosaurs such as Oryctodromeus , some ornithischian species seem to have led a partially fossorial burrowing lifestyle.

A good understanding of how dinosaurs moved on the ground is key to models of dinosaur behavior; the science of biomechanics, pioneered by Robert McNeill Alexander , has provided significant insight in this area.

For example, studies of the forces exerted by muscles and gravity on dinosaurs' skeletal structure have investigated how fast dinosaurs could run, [96] whether diplodocids could create sonic booms via whip -like tail snapping, [] and whether sauropods could float.

Modern birds are known to communicate using visual and auditory signals, and the wide diversity of visual display structures among fossil dinosaur groups, such as horns, frills, crests, sails, and feathers, suggests that visual communication has always been important in dinosaur biology.

Paleontologist Phil Senter has suggested that non-avian dinosaurs relied mostly on visual displays and possibly non-vocal acoustic sounds like hissing, jaw grinding or clapping, splashing and wing beating possible in winged maniraptoran dinosaurs.

He states they were unlikely to have been capable of vocalizing since their closest relatives, crocodilians and birds, use different means to vocalize, the former via the larynx and the latter through the unique syrinx , suggesting they evolved independently and their common ancestor was mute.

However, in contrast to Senter, other researchers have suggested that dinosaurs could vocalize and that the syrinx-based vocal system of birds evolved from a larynx-based one, rather than the two systems evolving independently.

Such vocalizations evolved independently in extant archosaurs numerous times, following increases in body size.

All dinosaurs laid amniotic eggs with hard shells made mostly of calcium carbonate. Most species create somewhat elaborate nests which can be cups, domes, plates, beds scrapes, mounds, or burrows.

Primitive birds and many non-avialan dinosaurs often lay eggs in communal nests, with males primarily incubating the eggs. While modern birds have only one functional oviduct and lay one egg at a time, more primitive birds and dinosaurs had two oviducts, like crocodiles.

Some non-avialan dinosaurs, such as Troodon , exhibited iterative laying, where the adult might lay a pair of eggs every one or two days, and then ensured simultaneous hatching by delaying brooding until all eggs were laid.

When laying eggs, females grow a special type of bone between the hard outer bone and the marrow of their limbs. This medullary bone, which is rich in calcium , is used to make eggshells.

A discovery of features in a Tyrannosaurus skeleton provided evidence of medullary bone in extinct dinosaurs and, for the first time, allowed paleontologists to establish the sex of a fossil dinosaur specimen.

Further research has found medullary bone in the carnosaur Allosaurus and the ornithopod Tenontosaurus. Because the line of dinosaurs that includes Allosaurus and Tyrannosaurus diverged from the line that led to Tenontosaurus very early in the evolution of dinosaurs, this suggests that the production of medullary tissue is a general characteristic of all dinosaurs.

Another widespread trait among modern birds but see below in regards to fossil groups and extant megapodes is parental care for young after hatching.

Jack Horner's discovery of a Maiasaura "good mother lizard" nesting ground in Montana demonstrated that parental care continued long after birth among ornithopods.

However, there is ample evidence of precociality or superprecociality among many dinosaur species, particularly theropods.

For instance, non- ornithuromorph birds have been abundantly demonstrated to have had slow growth rates, megapode -like egg burying behavior and the ability to fly soon after birth.

Genital structures are unlikely to fossilize as they lack scales that may allow preservation via pigmentation or residual calcium phosphate salts.

In , the best preserved specimen of a dinosaur's cloacal vent exterior was described for Psittacosaurus , demonstrating lateral swellings similar to crocodylian musk glands used in social displays by both sexes and pigmented regions which could also reflect a signalling function.

However, this specimen on its own does not offer enough information to determine whether this dinosaur had sexual signalling functions; it only supports the possibility.

Cloacal visual signalling can occur in either males or females in living birds, making it unlikely to be useful to determine sex for extinct dinosaurs.

Because both modern crocodilians and birds have four-chambered hearts albeit modified in crocodilians , it is likely that this is a trait shared by all archosaurs, including all dinosaurs.

Various researchers have supported dinosaurs as being endothermic, ectothermic "cold-blooded" , or somewhere in between. After non-avian dinosaurs were discovered, paleontologists first posited that they were ectothermic.

This was used to imply that the ancient dinosaurs were relatively slow, sluggish organisms, even though many modern reptiles are fast and light-footed despite relying on external sources of heat to regulate their body temperature.

The idea of dinosaurs as ectothermic remained a prevalent view until Robert T. Bakker , an early proponent of dinosaur endothermy, published an influential paper on the topic in Bakker specifically used anatomical and ecological evidence to argue that sauropods, which had hitherto been depicted as sprawling aquatic animals with their tails dragging on the ground, were endotherms that lived vigorous, terrestrial lives.

In , Bakker expanded on his arguments based on energy requirements and predator-prey ratios. One of the greatest contributions to the modern understanding of dinosaur physiology has been paleohistology , the study of microscopic tissue structure in dinosaurs.

Fibrolamellar bone was common in both dinosaurs and pterosaurs, [] [] though not universally present. In saurischian dinosaurs, higher metabolisms were supported by the evolution of the avian respiratory system, characterized by an extensive system of air sacs that extended the lungs and invaded many of the bones in the skeleton, making them hollow.

These traits may have enabled sauropods to grow quickly to gigantic sizes. Like other reptiles, dinosaurs are primarily uricotelic , that is, their kidneys extract nitrogenous wastes from their bloodstream and excrete it as uric acid instead of urea or ammonia via the ureters into the intestine.

This would have helped them to conserve water. The possibility that dinosaurs were the ancestors of birds was first suggested in by Thomas Henry Huxley.

Feathers are one of the most recognizable characteristics of modern birds, and a trait that was also shared by several non-avian dinosaurs.

Based on the current distribution of fossil evidence, it appears that feathers were an ancestral dinosaurian trait, though one that may have been selectively lost in some species.

Simple, branched, feather-like structures are known from heterodontosaurids , primitive neornithischians , [] and theropods, [] and primitive ceratopsians.

Evidence for true, vaned feathers similar to the flight feathers of modern birds has been found only in the theropod subgroup Maniraptora, which includes oviraptorosaurs, troodontids, dromaeosaurids, and birds.

Archaeopteryx was the first fossil found that revealed a potential connection between dinosaurs and birds. It is considered a transitional fossil , in that it displays features of both groups.

Brought to light just two years after Charles Darwin 's seminal On the Origin of Species , its discovery spurred the nascent debate between proponents of evolutionary biology and creationism.

This early bird is so dinosaur-like that, without a clear impression of feathers in the surrounding rock, at least one specimen was mistaken for the small theropod Compsognathus.

Most of these specimens were unearthed in the lagerstätte of the Yixian Formation, Liaoning , northeastern China, which was part of an island continent during the Cretaceous.

Though feathers have been found in only a few locations, it is possible that non-avian dinosaurs elsewhere in the world were also feathered.

The lack of widespread fossil evidence for feathered non-avian dinosaurs may be because delicate features like skin and feathers are seldom preserved by fossilization and thus often absent from the fossil record.

The description of feathered dinosaurs has not been without controversy; perhaps the most vocal critics have been Alan Feduccia and Theagarten Lingham-Soliar, who have proposed that some purported feather-like fossils are the result of the decomposition of collagenous fiber that underlaid the dinosaurs' skin, [] [] [] and that maniraptoran dinosaurs with vaned feathers were not actually dinosaurs, but convergent with dinosaurs.

Because feathers are often associated with birds, feathered dinosaurs are often touted as the missing link between birds and dinosaurs.

However, the multiple skeletal features also shared by the two groups represent another important line of evidence for paleontologists. Areas of the skeleton with important similarities include the neck, pubis, wrist semi-lunate carpal , arm and pectoral girdle , furcula wishbone , and breast bone.

Comparison of bird and dinosaur skeletons through cladistic analysis strengthens the case for the link. Large meat-eating dinosaurs had a complex system of air sacs similar to those found in modern birds, according to a investigation led by Patrick M.

The lungs of theropod dinosaurs carnivores that walked on two legs and had bird-like feet likely pumped air into hollow sacs in their skeletons, as is the case in birds.

CT scanning of Aerosteon' s fossil bones revealed evidence for the existence of air sacs within the animal's body cavity. Fossils of the troodonts Mei and Sinornithoides demonstrate that some dinosaurs slept with their heads tucked under their arms.

Several deinonychosaur and oviraptorosaur specimens have also been found preserved on top of their nests, likely brooding in a bird-like manner.

Some dinosaurs are known to have used gizzard stones like modern birds. These stones are swallowed by animals to aid digestion and break down food and hard fibers once they enter the stomach.

When found in association with fossils, gizzard stones are called gastroliths. All non-avian dinosaurs and most lineages of birds [] became extinct in a mass extinction event , called the Cretaceous—Paleogene K-Pg extinction event , at the end of the Cretaceous period.

Above the Cretaceous-Paleogene boundary , which has been dated to However, the specific mechanisms of the extinction event and the extent of its effects on dinosaurs are still areas of ongoing research.

Just before the K-Pg extinction event, the number of non-avian dinosaur species that existed globally has been estimated at between and Rock formations from the Maastrichtian epoch, which directly preceded the extinction, have been found to have lower diversity than the preceding Campanian epoch, which led to the prevailing view of a long-term decline in diversity.

The asteroid impact hypothesis , first brought to wide attention in by Walter Alvarez , Luis Alvarez , and colleagues, attributes the K-Pg extinction event to a bolide an extremely bright meteor impact.

Within hours, the Chicxulub impact would have created immediate effects such as earthquakes, [] tsunamis, [] and a global firestorm that likely killed unsheltered animals and started wildfires.

Within days, sulphate aerosols released from rocks at the impact site would have contributed to acid rain and ocean acidification.

At the time of the K-Pg extinction, the Deccan Traps flood basalts of India were actively erupting. The eruptions can be separated into three phases around the K-Pg boundary, two prior to the boundary and one after.

Before , arguments that the Deccan Traps eruptions—as opposed to the Chicxulub impact—caused the extinction were usually linked to the view that the extinction was gradual.

Prior to the discovery of the Chicxulub crater, the Deccan Traps were used to explain the global iridium layer; [] [] even after the crater's discovery, the impact was still thought to only have had a regional, not global, effect on the extinction event.

Walter Alvarez himself has acknowledged that the Deccan Traps and other ecological factors may have contributed to the extinctions in addition to the Chicxulub impact.

Whether the Deccan Traps were a major cause of the extinction, on par with the Chicxulub impact, remains uncertain.

Proponents consider the climatic impact of the sulphur dioxide released to have been on par with the Chicxulub impact, and also note the role of flood basalt volcanism in other mass extinctions like the Permian-Triassic extinction event.

They also contend that the causes of different mass extinctions should be assessed separately. Non-avian dinosaur remains have occasionally been found above the K-Pg boundary.

In , Spencer Lucas and colleagues reported the discovery of a single hadrosaur right femur in the San Juan Basin of New Mexico , and described it as evidence of Paleocene dinosaurs.

The rock unit in which the bone was discovered has been dated to the early Paleocene epoch, approximately This has been used to support the view that the K-Pg extinction was gradual.

By human standards, dinosaurs were creatures of fantastic appearance and often enormous size. As such, they have captured the popular imagination and become an enduring part of human culture.

The entry of the word "dinosaur" into the common vernacular reflects the animals' cultural importance: in English, "dinosaur" is commonly used to describe anything that is impractically large, obsolete, or bound for extinction.

Public enthusiasm for dinosaurs first developed in Victorian England, where in , three decades after the first scientific descriptions of dinosaur remains, a menagerie of lifelike dinosaur sculptures was unveiled in London 's Crystal Palace Park.

The Crystal Palace dinosaurs proved so popular that a strong market in smaller replicas soon developed.

In subsequent decades, dinosaur exhibits opened at parks and museums around the world, ensuring that successive generations would be introduced to the animals in an immersive and exciting way.

In the United States, for example, the competition between museums for public attention led directly to the Bone Wars of the s and s, during which a pair of feuding paleontologists made enormous scientific contributions.

The popular preoccupation with dinosaurs has ensured their appearance in literature , film , and other media.

Beginning in with a passing mention in Charles Dickens ' Bleak House , [] dinosaurs have been featured in large numbers of fictional works.

Jules Verne 's novel Journey to the Center of the Earth , Sir Arthur Conan Doyle 's book The Lost World , the animated film Gertie the Dinosaur featuring the first animated dinosaur , the iconic film King Kong , the Godzilla and its many sequels, the best-selling novel Jurassic Park by Michael Crichton and its film adaptation are just a few notable examples of dinosaur appearances in fiction.

Authors of general-interest non-fiction works about dinosaurs, including some prominent paleontologists, who have often sought to use the animals as a way to educate readers about science in general.

Dinosaurs are ubiquitous in advertising ; numerous companies have referenced dinosaurs in printed or televised advertisements, either in order to sell their own products or in order to characterize their rivals as slow-moving, dim-witted, or obsolete.

Closely related reptiles had legs positioned to the sides, with their body suspended between them, like a crocodile. A subtle change in anatomy allowed the legs of dinosaurs to be pulled beneath the body to act as towers rather than bridge supports.

He and Baylene dig until they find her some water. The rest of the herd follows suit, and Kron's sister Neera, impressed by Aladar's compassion, begins to grow closer to him, while Kron believes he wants to take over.

Meanwhile, two Carnotaurus have been tracking the herd. Kron's lieutenant Bruton reports the approaching predators after surviving an attack during a scouting mission, but Kron quickly ushers the herd away from the lake, leaving Bruton, Aladar, the lemurs, and the elderly dinosaurs behind.

The group takes shelter in a cave as night falls, but the predators catch up to them and attack. Bruton sacrifices his life to cause a cave-in that kills one of the Carnotaurus , forcing the survivor to retreat.

The group ventures deeper into the cave, but they reach a dead end. Though Aladar briefly loses hope, Baylene uses her strength to smash through the wall, and they arrive at the Nesting Grounds on the other side.

Eema notices that a landslide has blocked off the usual entrance to the valley. Aladar rushes off alone to find Kron trying to lead the herd over the landslide, unaware of the sheer drop on the other side.

Kron attacks Aladar, taking Aladar's warning as a challenge to his leadership, until Neera, fed up with Kron's illogical behavior, intervenes.

Realizing Kron's selfishness, the herd follows Aladar, while Kron stubbornly tries to climb the rocks by himself.

The hungry Carnotaurus arrives, but Aladar rallies everyone to stand together in defiance against it. The Carnotaurus is frightened off, and pursues Kron instead.

Aladar and Neera rush to save him, but fail to get there in time. They avenge Kron by forcing the Carnotaurus over the sheer drop to its death.

Aladar then leads the herd back to the Nesting Grounds. Sometime later, a new generation of dinosaurs hatches, among them Aladar and Neera's children.

The initial idea for the film originated in during the filming of Robocop in which Phil Tippett recommended to director Paul Verhoeven that they should produce a "dinosaur picture".

Verhoeven responded positively to the idea and suggested an approach inspired by Shane in which "you follow a lead character through a number of situations and moving from a devastated landscape into a promised land.

In , the project began development in Disney's live-action division in which Verhoeven and Tippett had originally planned to use stop motion animation techniques such as puppets, scale models, and miniatures.

The film was originally going to be much darker and violent in tone, in a style akin to a nature documentary. After Woot defeats Grozni in a final fight, the film would end with the Cretaceous-Paleogene extinction event , which would ultimately result in the deaths of the main dinosaur characters.

Smith became involved in the film and briefly became the director following Verhoeven's and Tippett's departure.

Reflecting on his tenure, Smith said that "Jeanne Rosenberg was still writing the script, but it was in trouble. Disney wanted a cute story of dinosaurs talking, and I didn't like the idea.

I thought it should be more like Jean Annaud 's The Bear. I wanted to have actual lemurs in it. They actually existed at the time of dinosaurs We actually located a guy who trains them.
