Pics of Prehistoric Creatures Thread

[HammerBioLizard]

Hello world!

In this thread we post pics of prehistoric creatures and then describe them.


This is Amargasaurus. It is a herbivorous sauropod from early Cretaceous Argentina. Its fossiles have been found in the La Amarga Foundation, hence its name. It had spikes coming out of its neck. These spikes may have supported a sail. It was 10 meters long and 2.7 meters tall.

It is the inspiration behind Aurorus from Pokemon X and Y.

Hello world!

Kinda a cool you like this stuff so much. Fossils do interest me much.

This is a Dunkleosteus. It is a prehistoric fish. It lived in the Late Devonian period and its fossils have been found in many parts of the world. The largest Dunkleosteus were 6 meters long.

Dunkleosteus was a fierce predator of the prehistoric seas. It had a sharp beak instead of proper teeth. It was rather slow-moving compared to modern sharks due to its thick bones.

this is a sort of rhetoric that annoys me from the left and i think there's good strategic reasons to abandon it, but i couldn't resist the joke

This is Eurotamandua. Eurotamandua was an insect-eating mammal which lived in Germany during the early Eocene. It was 90 centimeters long.

Most scientists think that Eurotamandua is related to South American anteaters because it looks like one. Other scientists believe that Eurotamandua cannot be an anteater because it lived too far away from South America. These scientists believe that Eurotamandua is an early pangolin that doesn't have scales yet.

Hello world!

This thread doesn't seem to be getting much love. I'm going to keep posting here.




This is Paraceratherium. It lived all across Eurasia during the Oligocene. It was 4.8 meters tall and 7.4 meters long. It weighed between 15 and 20 metric tons. It is the largest terrestrial mammal known to science. Some of its vertebrae contained hollow parts, to keep the weight down. The same adaption was seen in Sauropods, millions of years earlier.

Paraceratherium was a perissodactyl. Its closest living relatives are the Horse, Zebra, Donkey, Rhino and Tapir.

Megalania.

A very large monitor lizard that died out some time in the past 50,000 years.

Meaning that it co-existed with Australia's earliest human inhabitants for some period of time.

Australia's indigenous people were telling stories about the megalania, about hunting for it and about how bad it apparently smelled, long before fossils were discovered. It was believed to be a myth.

My guess is that the megalania died out gradually, and that there were a few isolated creatures around until a few thousand years ago.

Marsupial Lion.

A large one would have been comparable to a lioness in size.

It lived until at least 46,000 years ago, meaning that it co-existed with humans for some time.

Its skull was apparently highly specialised for killing large game, meaning that it may have died out because humans hunted large game to extinction leaving small-to-medium game which the marsupial lion found more difficult to catch.

The legend of the Australian "Drop Bear" is likely based on these ambush hunters.

Hello world!

I'm glad to see that this thread has started up again.



This is Zalambdalestes. It lived in Mongolia during the Late Cretaceous. It was 20 centimeters long. Its teeth were perfect for eating insects. It was a predator, but it likely was not at the top of the food chain, given that it coexisted with the last dinosaurs.

Its reproductive system didn't fossilize, so its method of reproduction is unknown. It probably gave birth to underdeveloped joeys like a modern marsupial but this has not be proven conclusively.
