Friday's Mystery Fossil

HINT: The feature running across the top of the picture will tell you what kind of (vertebrate) animal it is and the feature in the bottom right hand corner will narrow down the group.

Tough one! Any guesses?

Congratulations to Mambo Bob for his response. Friday's Mystery Fossil was indeed a theropod and specifically a Tyrannosaurus but not Sue of the Chicago Field Museum. Rather, the picture is of a specimen at Palais de la découverte in Paris. Also, points Malacoda for his imaginative guess (an obvious asset in palaeontology:)

The image may be familiar to some as it was featured in my January posting, CSI: Garfield County.

HINT: Because this photo isn't at a high enough resolution, you cannot see the fine serrations on edges of the individual elements.

Come on, this one isn't too hard. Any guesses?
