The painting depicts four primitive horses (Propalaeotherium) – two at the top and two at the bottom – with the one on the top left looking at the viewer, whilst the one on the right is feeding on the ground; of the two at the bottom, one is running to the left and the other to the right; all the animals have dark legs and muzzles, their manes are short and black, their bellies are light in colour, and the rest of their bodies are a beautiful, rich brown

New experiments indicate bird-like oviraptorid dinosaurs could not fully warm their eggs with body heat alone, instead combining brooding with solar warmth in semi-open nests.

Fossils show exceptionally rare evidence of a cloacal vent—the slit that most vertebrates use to excrete, have sex and lay egg—which could shed light on the evolution of the orifice

Osteichthyans--the bony fishes--are by far the most diverse group of living jawed vertebrates. Two papers out today in @nature.com feature remarkable new Chinese fossils that paint a picture of substantial morphological diversity among stem osteichthyans.

Cephalopods are nothing to be afraid of. They don't see humans as prey, so they probably wouldn't hurt you But Humboldt squids (Dosidicus gigas) are big squids with a reputation for being aggressive, so I would be pretty scared if one grabbed by like this 🦑📷ferleys (inaturalist.ca/observations...)
A POV shot of a Humboldt Squid (Dosidicus gigas) grabbing a divers arm and camera. Two arms are raised up and curling back, two are grabbing the camera or are about to, and the other arms are out of the shot. The squid is quite large, and its mantle is pointing away from the camera. Some fish are in the background. The whole image has a green tint.
