Mary Anning

In 1811 , or 1812, a young girl by the name of Mary Anning, along with her little brother, happened upon an incredible find while digging around the cliffs of Lyme Regis in England.   It was a skull. A very large skull. Four feet long and with jagged teeth. Mary kept looking. Her efforts paid off and she soon found the rest of the great beast. A large skeleton of a creature never before seen. They sold the skeleton to a local collector who eventually sold it to Charles Konig, then keeper of the department of natural history at the British Museum. Konig had even given it a name. He called it an Ichthyosaurus.

Mary’s success was that she was simply very good at what she did.  A jutting stone might be the snout of a plesiosaur, a flat piece of slate a flipper. It might even be the head of a pterosaur. Which it was in 1828 when Mary pulled the fossil of a pterosaur out of the cliffs.

Warm Blooded Dinosaurs

Episode 33In 1986 Professor Robert Bakker, a paleontologist,  published The Dinosaur Heresies.  According to Professor Bakker there have been waves of extinction, and these extinction events mainly attacked, or affected, one particular type of animal… warm blooded animals.  And it didn’t only happen once.  Since the appearance of dinosaurs there have been ten such extinction events. 

Birds descended from dinosaurs.  They are mammals like us. Somewhere along the line reptiles evolved from cold blooded creatures to warm blooded creatures. Perhaps Professor Bakker is on to something.  In this episode we will take a look at some of the arguments that support his theory.

Where Are the Dinosaurs?

Where are the DinsoaursWhat killed off the dinosaurs? There are many competing theories yet there is no ‘smoking gun’. There is evidence however, and with each bit of evidence comes another theory.  Dinosaurs didn’t disappear overnight. It took a few millions years for them to die out. Perhaps six million years. 

Theories offered to explain their demise include climate change, and volcanic activity. One of the more popular theories describes an impact event that involved an asteroid.  The resulting collision would have been catastrophic. Debris thrown into the atmosphere would have covered the earth and would have prevented sunlight from reaching the ground. After the dust had settled, greenhouse gases would then cause the temperatures to skyrocket. Plants would have died and so too, eventually, would the dinosaurs.
