Jurassic-era mammalian relative found with 38 of its babies’ skulls

Although this mammalian forerunner still reproduced like a reptile, the fossils shed much light on our own evolution.

Early mammal fossil shows how the Pangaea supercontinent split up

Talk about a groundbreaking discovery.

10 of the Weirdest Prehistoric Creatures

Eons ago, many millennia before written history, bizarre animals roamed the Earth.

This rat-like creature is the earliest ancestor of mankind

In a way, we’re all the descendants of these rats.

The American pika is being killed off by climate change

They may be the cutest animal in the country, but we’re cooking the d’awww out of them.

Great Barrier Reef rodent becomes first extinct mammal at the hand of climate change

Great Barrier Reef’s only endemic mammal, the Bramble Cay melomys, is now officially extinct, scientists say.

Brilliant GIF shows how Humans, Birds and Insects Breathe

Three different ways to breathe: Mammals, birds and insects breathe in different ways, as exemplified above. Humans, as mammals, inhale by moving the diaphragm to lower the air pressure in the chest cavity and pull air into the lungs. The human chest cavity is always at a lower pressure than the outside environment. Birds on the other hand, have air

Colugo (flying lemur): the most accomplished and cutest mammalian glider

It seems like us mammals were never meant to fly. Sure, bats can fly, but that’s kind of it. Even so, some mammals have learned alternative means of skipping at an altitude: gliding (feather-tailed possums, sifaka) or parachuting (cats). Yes, cats parachute, but enough of them. Chances have it you’ve seen on average 17 cats already since morning. Today’s post is about a gliding mammal that’s in much more need of attention: the adorable colugos.

Earliest tree-clinging and burrowing mammals show they weren’t afraid of dinosaurs

Although mammals surfaced only 20 million years after the first dinosaurs evolved, there’s a general consensus that mammals were shadowed and reclusive in the face of dinosaurs, seeing how they were the dominant animals on the planet back then. As such, early mammals are thought to have been mostly nocturnal with minimal interaction with dinosaur environments, occupying very limited ecological niches. This conventional thinking might be toppled by recent findings made by Chinese paleontologists who discovered two highly sophisticated early mammals each at least 160 million years old: the first tree-clinging mammal and the first burrowing mammal. These creatures munched on the same plants dinosaurs did, proving they seemingly coexisted in the same ecological framework.

New fossils throw mammalian family tree into disarray

A fossil of a small, forest-floor-dwelling animal called Megaconus puts a big question mark on the evolution of mammals – it suggests that its group predated animals, while another one, from its tree dwelling ‘cousing’ Arboroharamiya shows the group belonged to the mammals. The two fossils have paleontologists scratching their heads, not knowing where to place them in the family

Mammals Can ‘Choose’ Sex of Offspring, Study Finds

An extremely challenging study published by a team of researchers from the Stanford School of Medicine claims that through some unknown mechanism mammals can biasĀ  the sex of their offspring in order to win the genetic lottery and produce extra grandchildren. The holy graal of modern evolutionary biology After analyzing 90 years of breeding records from the San Diego Zoo,

Earliest mammal pinpointed suggests the ancestry expanded after dinosaurs died off

For the past twenty years there’s been a debate whether the mammal explosion that eventually made the class of animals dominant on Earth happened before or after the end of the dinosaur reign. Scientific papers and various evidence supporting both views have surfaced along the years, but a recent massive study conducted by a collaborative team of scientists may have

Dracula mammal lived with the dinosaurs in Transylvania

Well it may be a bit of overreaction, but with the Halloween and all, you just have to call it: 70 million year old mammal had long, oversized, blood-red teeth, scurrying at the feet of dinosaurs. The discovery of a new skull now gives new insight into his diet and habits. Barbatodon transylvanicus lived in what is today Transylvania, Romania,

Sabre tooth ferret like mammal unearthed in Patagonia

A recent discovery of an extinct mammal called Cronopia promises to help scientists trace the ascent and spread of mammals. Even though it looks rather taken from a cartoon than from reality, Cronopio dentiacutus was the real deal. It had a long snout, huge sharp canines, and a powerful set of jaw muscles to bite and chew its prey. The

Mammals, half way extinct??

The previous 5 mass extinctions wiped out more than three quarters of the world’s animals, and if things continue to move in the same way, the same thing will happen in North America, according to a University of California, Berkeley, and Pennsylvania State University analysis. Numerous scientists have warned that the direction things are moving in is way more dangerous

Blue whales singing lower every year, baffled scientists say

Blue whales are not only the biggest living creatures in the world right now, but the biggest ever to have ‘walked’ the face of the earth; they’re also the loudest for that matter. After recovering from near extinction in the beginning of the 20th century, blue whales are finally getting a part of the respect they deserve. However, researchers cannot
