Were Crocodiles Responsible For The Stones We Call Tools?

Bob O’H brings an interesting Correspondence item in Nature to our attention. An excerpt is below:

Crocodylian Snout Shape, Mammalian Carnivora, and Hominins

Crocodylians have a long and complex evolutionary history. More importantly, we have a large number of crocodylian fossils. I bring this up because of a number of interesting papers I have read recently that all have a common theme. In this post I will take a look at a paper by Christopher Brochu published in 2001 in the American Zoologist (Crocodylian Snouts in Space and Time: Phylogenetic Approaches Toward Adaptive Radiation, Amer. Zool., 41:564-585 [2001]).
