For the first time in a major film, dinosaurs were portrayed as intelligent, agile, warm-blooded animals, rather than lumbering monsters more common to older films. Jack Horner was a consultant, and the artwork of Gregory Paul, Mark Hallett, Doug Henderson, and John Gurche were used in pre-production. [32]
The dinosauroid theory, along with the often repeated fact that Troodontids were the most intelligent dinosaurs, may have led to an overestimation of its intelligence among the general public; while Stenonychosaurus did have a larger brain to body ratio when compared to other theropod dinosaurs of its time, its intelligence was likely ...
While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...
Surmising even the physical appearance of a dinosaur - or any extinct animal - based on its fossils is a tricky proposition, with so many uncertainties involved. Assessing a dinosaur's ...
A new study, based on fossils from 1,000 dinosaur species and paleoclimate information, found that the three main dinosaur groups adapted differently, with two of the groups evolving the ability ...
Major extinctions in terrestrial vertebrates and large amphibians. Earliest examples of armoured dinosaurs. 195 Ma First pterosaurs with specialized feeding (Dorygnathus). First sauropod dinosaurs. Diversification in small, ornithischian dinosaurs: heterodontosaurids, fabrosaurids, and scelidosaurids. 190 Ma Pliosauroids appear in the fossil ...
In 1977 James Hopson introduced the use of estimated encephalization quotients to the topic of dinosaur intelligence, finding Edmontosaurus to have an EQ of 1.5, above that of other ornithischians including earlier relatives like Camptosaurus and Iguanodon and similar to that of carnosaurian theropods and modern crocodilians but below that of ...
The eponymous Silurians on Doctor Who are a race of reptilian humanoids from Earth's past, making their first appearance in the show in 1970. Frank and Schmidt cite Inherit the Stars, a 1977 novel by J. P. Hogan as containing a similar hypothesis, but also say they were surprised by how rarely the concept was explored in science fiction.
