Paleontology Tank Tops

Akylosaurus, it’s name means the “fused lizard.” This big guy was the largest known member of a group of the most heavily armored dinosaurs ever to have lived, most of it’s body was covered in large osteoderms (bony hard scales, or plates), this armor was so impenetrable that some scientists think that they might have had armored eye lids. Ankylosaurus lived during the Late Cretaceous at around 68 to 66 million years ago. The largest specimens found to date probably weight in at a maximum of 4.4 – 7.9 tons, and sported a large tail weapon (or club) that could be up to around 2 feet wide and could easily shatter bone, easily able to shatter the leg bones of big predators like Tyrannosaurus Rex.

For the Triceratops, "Ceratopsian" is the fancy word for "horned face".

A small early sauropod from Sichuan province in China, Shunosaurus is best known for the strange bony club at the end of its tail.

Roughly 76 to 75 million years ago during the Late Cretaceous period, large herds of an animal now known as Lambeosaurus congregated around the shallow rivers that ran through what is now Alberta, Canada. These beasts could be up to 31 feet long, and weigh up to 3 and a quarter tons, they would mostly walk on all fours, switching to two when speed was required, their huge tails stiffly hanging in the air behind them, making up nearly half of their length. On their heads, they sported large, flamboyant crests, the males likely sporting ones larger and more complex than those of the females.

Smilodon (or 2-edged knife tooth) is better known as the famous saber-toothed cat, it is an extinct species of large cat common to the Americas during the Pleistocene epoch, from 2.5 million years to 10,000 years ago. There were three species, S. gracilis (weighing in at around 120-220lbs), S. fatalis (350-620lbs), and a South American species S. populator (490-880lbs). All saber-toothed cats were defined by their distinctive long canine teeth measuring around 11 inches in length, which they used in hunting large herbivores like bison, camels, and small horses, and even mammoths.
