Issi saaneq means "cold bones" in Greenland's indigenous Kalaallisut language. This particular Late Triassic plateosaurid is warming it's bones in a mud hot spring. Not only is the mud soothing, but it helps to ward off parasites.#DrawDinovember

Ancient fish are so strange and and fascinating. Furcacauda is a Lower Devonian (400 MYA) jawless fish who's fossils were found in Canada. The eyespots I put on them are purely speculative,but that nautiloid does think it's looking in a mirror.

The Late Triassic (230 MYA) archosaur Poposaurus gracilis is more closely related to living crocodilians than dinosaurs, despite being a swift biped. This one is about to scavenge on a temnospondyl that recently passed away.

Don't worry Zhanghenglong, this isn't the big one, just a close call. This hadrosaurid iguanodont is safe for now, as it's an another 20 million yrs before for the asteroid that caused the extinction of the dinosaurs hits the Earth.

Keep moving Albertosaurus. This mother Quetzalcoatalus stands guard over her emerging flaplings. They may be small and vulnerable now, but once fully grown they will be that largest flying animal that has ever existed with a 33-36 ft wingspan.

A large Eurypterus caught in a wave on a Silurian sea (420 MYA). Commonly called "sea scorpions" certain species of this group were the largest arthropods that ever lived with Jaekelopterus est. to reach up to 8.5 feet long.
