    Decades ago, scientists explained that a fossilized pregnant ichthyosaur exploded after dying. Today, paleotaphonomists revisit the exploded mother in a new light.

    Explanation of the decades-old theory of explosion, and why it doesn't apply here:

    Crocodylomorpha: Goniopholididae

    Curnoe's recent find spawns a question: What is it that makes us Homo sapiens?
    Darren Curnoe's recent discovery of a new form of human makes him think a little harder about whether to call it Homo sapiens or something else.

    Paleoanthropologists have discovered a population of humans that's distinctively different from the ones that lived in that part of the world during that period of time.

    A few weeks ago, we heard that Tyrannosaurus sported the most powerful bite of any land animal. Dunkleosteus sported the most powerful bite in all history.

    Time for Rex and the bone-headed fish to move over. The king of all bite force and his royal family want to reclaim their glory. Enter Crocodilians, unquestionably the most powerful biters ever to live on the planet. Deinosuchus wasn't included in the study, but the analyses of living crocodilians leads the researchers to believe that Deinosuchus was obviously the most powerful biter ever.

    Theropoda: Tyrannosauroidea
    The People's Republic of China has yielded one of our most anticipated discoveries-- an adult tyrannosaur that answers the question of whether feathers appeared on the larger adult theropods. Perhaps we'll find out about Tyrannosaurus soon enough as well?

    Carnotaurus had a large tail muscle that made it efficient at running. Watch out, smaller dinosaurs! However, the tail muscle was enclosed by a cagelike structure that meant the dinosaur was terrible at maneuvering when not running in a straight line.

    Manatees and dugongs today have ranges that don't overlap. But their ancestors were frequently sympatric; that is, there was a level of diversity in manatees and dugongs within a given ecosystem.

    Leakey pleased to hear his prediction of oil in Kenya is correct
    Nearly 40 years ago, paleoanthropologist Richard Leakey found dinosaurs in Kenya and guessed there must have been a natural oil reservoir nearby. Kenya has just discovered Leakey's oil reserve, and Leakey is happy to hear this. But what else does he have to say on this?
