Live from the fossil field!

Dr. Bakker’s drawing of a Dimetrodon fighting a Xenacanth
illustrates E.C. Olson’s theory of what really went on in the
Permian – and how Xenacanth might have defended itself against
the biggest predator the world had ever seen.

Our paleontology team – led by Dr. Robert Bakker – is back in Seymour, TX this week, digging for Dimetrodon at a site they’ve now been working for several years. (You can read more of what’s been found already in our daily blog from the field in 2007).

They’ve found Dimetrodon – the T. rex of its day – all over the site. They’ve brought back jacket after jacket of fin spines, vertebra columns, even skulls of this species, for study. But – and this is the mystery – not a whole lot of herbivores. So – what was Dimetrodon eating?

The theory put forth by E.C. Olson is that they were eating Xenacanth (freshwater sharks) that swam in the shallow seas present in the area during the Permian. And the team has found evidence to that effect – in the form of chewed up shark skull in the area. But they’re still after the smoking gun that would prove Olson’s theory definitively.

Twelve or so of our best diggers have made this their mission this week – and one of them will be checking in with us every day. Today, Kat Havens – one of our regular bloggers here – fills us in on what was found. Listen closely – it’s pretty cool.

Check back soon – more news from the field tomorrow!
