Welcome to the BIOL1030 3D model viewer! This should be an easy exercise – simply click on the links in green and use our fingers or mouse to rotate the specimen. We’ll discuss all specimen comparisons as we go through the lexture.

NB: if all of you log in at the same time, you might experience a delay in model loading – there’s a lot of you :-).

One of the best examples of convergence is the uncanny resemblance between domestic dogs and the completely unrelated Tasmanian tigers (or Thylacines): Grey wolf vs. Thylacine

Compare a giant carnivorous synapsid (members of the lineage leading to mammals) of the Permian with a crocodile (this is a living Mexican crocodile, but they look pretty similar to Triassic species): Dimetrodon (left) vs. Crocodile (right)!

After the crocodile heyday of the Triassic, Dinosaurs took over after the Triassic-Jurassic extinction. The most crocodile-ey they got was this this extremely caiman-like aquatic dinosaur Baryonyx!

When the Cretaceous came to a fiery end with the meteorite strike, large horned herbivores re-evolved multiple times. We picked a large herbivorous dinosaur, Triceratops horridus, to compare to an extinct, rhino-sized hoofed animal- Arsinoitherium: Triceratops (left) vs. Arsinoitherium (right)
