Eight of the Most Nightmarish Prehistoric Animals

There's been life on earth for about four billion years, and a lot of it has been freaking terrifying. Great job, evolution, we’ll all be having bad dreams tonight. 1. Basilosaurus basilosaurus.png © The Field Museum, GEO86500_166d, Photographer Karen Carr, artist.

Inside the World of the Elusive Vampire Squid

Vampire squids live in a world totally alien to us, and almost qualify as alien themselves. They spend most of their lives floating in the ocean’s deep, dark, midwater depths that don’t have much oxygen. A vampire squid brought onboard a ship by a trawl is black with a huge pointed beak—an infernal appearance if there ever was one. Despite their threatening appearance, studies of this ancient group (we think they had their heyday during the time of the dinosaurs) have improved our knowledge of cephalopod evolution.

Chihuahua-sized fossil "beardogs" shed new light on evolution of dogs and their relatives

Fossil discoveries don’t always happen out in the field, with scientists armed with pick-axes realizing they’ve found something special. Sometimes, fossils lie in wait in museum collections until the right researcher comes along and realizes there’s something unusual about them. That’s what happened this time, and the fossils in question are prehistoric dog relatives called “beardogs.”
