Entombed within the 9 to 10 million year old rocks at Cerro de los Batallones in Spain’s Madrid Basin are at least nine different assemblages of large fossil mammals. Two of these deposits are rich in carnivore bones, and provide an interesting snapshot at how these apex predators coexisted.

X-Rays Reveal More of Fossil Record

X-Rays Reveal More of Fossil Record

Soft tissues, like skin and feathers, aren’t usually part of the fossil record, but a new technique has found a way to bring some of them back into the record. The technique was used to resurrect the teeth and recognize the carcass of a 50-million-year-old fossil of a lizard, long thought to be merely preserved remnants of skin shed from the reptile.

Pound-for-Pound, Megapiranha Out Bites T. Rex

Megapiranha's Bite Force Unmatched Among Vertebrates

Megapiranha is an extinct genus of serrasalmid characin fish that lived 8 to 10 million years ago, in the Late Miocene. It’s estimated to have reached lengths of up to 1.3 meters, which is about four times the size of piranha alive today. These estimates are based upon fossil specimens that have been discovered.

Neolithic Pottery Reveals Cheese-Making from 7,500 Years Ago

feta-cheese

A team of scientists from Princeton University and the University of Bristol, UK, have discovered traces of dairy fat in ancient ceramic fragments, indicating that humans have been making cheese in Europe for up to 7,500 years. Early dairy farmers probably devised cheese-making as a way to preserve milk.
