Happy Fossil Friday! Meet Edmontonia rugosidens, one of the tank-like ankylosaurs that lived in the late Cretaceous period some 75 million years ago. This image, snapped circa 1922, depicts a Museum preparator readying this specimen for display.

Ankylosaurs like Edomontonia were four-legged, plant-eating ornithischians whose short, massive bodies were covered with small bones set in a flexible skin. The ankylosaurs were the most completely armored of all the dinosaurs—some even sported spikes along the side of the body and a club at the end of the tail! This well-preserved specimen of Edmontonia was collected in Alberta, Canada in 1917 and is positioned with an upright posture, not with the sprawling, lizardlike limb posture it was once thought to have. See it up close in the Museum’s Hall of Ornithischian Dinosaurs!

It’s a bird! It’s a plane! It’s… a dinosaur? Nope to all of the above. This Fossil Friday, let’s talk about pterosaurs—the first animals with bones to evolve powered flight. Though they were related to dinosaurs, pterosaurs evolved on a separate branch of the reptile family tree. They ruled the skies for more than 150 million years, evolving into dozens of different species. Some were as small as a paper airplane while others, like Pteranodon pictured here in the Museum's Hall of Late Dinosaurs circa 1940-1960, had a wingspan of more than 20 ft (6 m). To see this prehistoric specimen, and more, plan your visit.

I got some vintage scrap pictures (Glanzbild) of dinosaurs and other prehistoric animals from 60s or 70s and they have the names of the animals printed on the other side. Now my question is, does anyone know why the Triceratops is simply labeled as "the ancestor of rhinoceros"?

As far as I know, when the first fossils of Triceratops were found it was thouht that they belonged to some kind of bison but it was soon found put that the fossil was actually a dinosaur, right? And it was never thought that rhinos evolved from dinosaurs?

Like all the others are simply 'Brontosaurus', 'Dimetrodon', 'Stegosaurus', 'Tyrannosaurus', 'Ichthyosaurus', 'Ophiacodor', and... okay well the last one also doesn't have a name and it is just 'Riesenechse (Urzeittier)' but the picture is some kind of gharial looking animal.

And then there's the majestic ancestor of rhinoceros:

In the mood for a blast from the past? This Throwback Thursday, check out an archival image from the Museum’s digital collections. Snapped in 1938, it depicts Museum preparators sculpting a model Styracosaurus. This large ceratopsian dinosaur was related to Triceratops. However, unlike its three-horned cousin, Styracosaurus had a singular nasal horn. It also possessed huge spikes on its frill—the bony collar that projects rearward from the skull. The model pictured here isn't on display today, but Styracosaurus fans can spot a fossil skeleton in the Hall of Ornithischian Dinosaurs.
