A model of the hypothetical dinosauroid, Dinosaur Museum, Dorchester The dinosauroid is a hypothetical species created by Dale A. Russell in 1982. Russell theorized that if a dinosaur such as Stenonychosaurus had not perished in the Cretaceous–Paleogene extinction event, its descendants might have evolved to fill the same ecological niche as humans.

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 ...
Many dinosaurs were quite small, some measuring about 50 centimeters (20 inches) in length. The first dinosaur fossils were recognized in the early 19th century, with the name "dinosaur" (meaning "terrible lizard") being coined by Sir Richard Owen in 1842 to refer to these "great fossil lizards".

With that, the first dinosaur was officially recognized, though the actual word dinosaur would not be coined until the 1840s The first dinosaur was named 200 years ago. We know so much more now
Its discovery helped researchers realize that dinosaurs were active, warm-blooded animals, kicking off the Dinosaur Renaissance: Denversaurus: 1988 Lance Formation (Late Cretaceous, Maastrichtian) United States ( South Dakota Wyoming) The youngest known nodosaurid [28] Diabloceratops: 2010 Wahweap Formation (Late Cretaceous, Campanian) United ...
Utahraptor (meaning "Utah's predator") is a genus of large dromaeosaurid (a group of feathered carnivorous theropods) dinosaur that lived during the Early Cretaceous period from around 135 to 130 million years ago in what is now the United States.
“Some of the earliest mammals were forced to live toward the bottom of the food chain and have likely spent 100 million years during the age of the dinosaurs evolving to survive through rapid ...
