A battle of the vampires, 20 million years ago?
They are tiny, ugly, disease-carrying little blood-suckers that most people have never seen or heard of, but a new discovery in a one-of-a-kind fossil shows that “bat flies” have been doing their noxious business with bats for at least 20 million years.

New species of ancient crocodile discovered; ‘Sheildcroc’ was ancestor of today’s species
A new species of prehistoric crocodile has been discovered. The extinct creature, nicknamed “Shieldcroc” due to a thick-skinned shield on its head, is an ancestor of today’s crocodiles.

Severe python damage to Florida’s native Everglades animals documented in new study
Precipitous declines in formerly common mammals in Everglades National Park in Florida have been linked to the presence of invasive Burmese pythons, according to new research. The study, the first to document the ecological impacts of this invasive species, strongly supports that animal communities in the 1.5-million-acre park have been markedly altered by the introduction of pythons within 11 years of their establishment as an invasive species. Mid-sized mammals are the most dramatically affected, but some Everglades pythons are as large as 16 feet long, and their prey have included animals as large as deer and alligators.

Livestock, not Mongolian gazelles, drive foot-and-mouth disease outbreaks
Wildlife health experts from the Wildlife Conservation Society have published evidence which supports the conclusion that Mongolian gazelles — one of the most populous large land mammals on the planet — are not a reservoir of foot-and-mouth disease, a highly contagious viral disease that threatens both wildlife and livestock in Asia.

Mammals shrink at faster rates than they grow: Research helps explain large-scale size changes and recovery from mass extinctions
It took about 10 million generations for terrestrial mammals to hit their maximum mass: that’s about the size of a cat evolving into the size of an elephant. Sea mammals, such as whales took about half the number of generations to hit their maximum.
