I play a very aggressive Therizinosaurus.

His name is Timmy Tickles.

Tyrannosaurus Rex Tooth Late Cretaceous Period (approx. 67 million years ago) Lance Formation, Niobrara County, Wyoming, USA

A LARGE AND WELL-PRESERVED TOOTH FROM THE MOST FEARSOME PREDATOR EVER TO WALK THE EARTH

No animal elicits the combination of fascination, reverence, and fear quite like that of Tyrannosaurus rex, the "tyrant lizard king." Dominating the western landscape of Late Cretaceous North America, T. rex's five-foot-long skull was packed with 60 teeth and featured a bone-crushing bite force of nearly 13,000 pounds (5,900 kg) per square inch, the strongest of any terrestrial animal other than its ancestor, Gorgosaurus. In comparison to other carnivorous theropods, T. rex teeth are proportionately huge. Robust and thickly-enameled crowns strengthened dozens of teeth, with serrations on both the posterior and anterior edges. The almost unrivaled power of this 40-foot-long (12.2 m) apex predator allowed it to hunt virtually every large dinosaur in its environment, including Triceratops, Ankylosaurus, Ornithomimus, Pachycephalosaurus, Edmontosaurus, and even other tyrannosaurs.

Spinosaurus, equipped with aquatic adaptations like crocodile-like jaws, webbed feet, has led some researchers to propose that it was predominantly an aquatic predator rather than a terrestrial one.

Spinosaurus is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian to Upper Turonian stages of the Late Cretaceous period, about 99 to 93.5 million years ago.

The genus was first known from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915.

The original remains were destroyed in World War II but additional material came to light in the early 21st century.

It is unclear whether one or two species are represented in the fossils reported in the scientific literature.

Spinosaurus, which was longer and heavier than Tyrannosaurus, is the largest known carnivorous dinosaur.

It possessed a skull 1.75 metres (roughly 6 feet) long, a body length of 14–18 metres (46–59 feet), and an estimated mass of 12,000–20,000 kg (13–22 tons).

It’s Fossil Friday! If you’ve been inside the Museum’s Hall of Vertebrate Origins, you may have noticed this marine reptile hanging overhead. Meet Thalassomedon haringtoni, a long-necked plesiosaur that lived during the Late Cretaceous some 85 million years ago. This behemoth had a relatively small head and many sharp teeth. Its long, flexible neck probably helped in grasping rapidly moving prey. Plesiosaurs, a group related to lizards, lived in the sea. Although they weren’t dinosaurs, they became extinct at the end of the Cretaceous around 65 million years ago, at the same time as the non-avian dinosaurs.

The Museum is open daily from 10 am–5:30 pm! Plan your visit.

Dinovember 2024 Day 11: The Ancient Herds

A scene inspired by the bonebed finds of the Dinosaur Park Formation of Alberta, Canada - As the dry season hits hard, a herd of Centrosaurus apertus daringly cross a river in order to reach a pasture of green ferns on the other side, and only a lucky few of these ornately-horned ceratopsians will succeed in completing this arduous task.

The iconic Tyrannosaurus rex on a Saturday morning 🦖 Realized that I haven’t made a serious attempt to draw t-rex since the nineties! 😳

[velespaleoart]

The smell of rain fills the air, though not a single drop has fallen. A huge Mosasaurus slowly swims through a warm, shallow sea, unbothered by the noisy pterosaurs.

The world seems half asleep.

Everything is gray.

Little scene sketch I did instdead of working in art class 🫡 I hope i can make a living out of it though ...haha...

velociraptor Mother and evil evil velociraptor child .. embarassingly bad at paleo art for someone with ''paleo'' in their username... to my defense as much as i enjoy dinosaurs ive never been a big fan of drawing animals

this is also like my 2nd digital dinosaur piece ever dont jump at m

How to see dinosaurs:

1.) Travel 66 million light years away from Earth.

2.) Look at Earth through a telescope.

3.) Dinosaurs.

Why not start a new month of the year with a newly-discovered dinosaur species? Meet Lokiceratops rangiformis, a fantastic exemplar of the rich ceratopsian diversity in Laramidia during the Campanian stage of the Late Cretaceous. A 6-meter-long centrosaurine ceratopsian with a 2-meter-long skull, it lived about 78.1 million years ago in what is now Montana’s Judith River Formation and appears to be most closely related to the slightly-younger Medusacertops lokii from the same formation and Albertaceratops nesmoi from Alberta’s Oldman Formation. The three species all together constitute the newly-created subgroup Albertaceratopsini within the Centrosaurinae.
