Richard Owen would have bristled at any linkage of creodonts and humans. Yet Owen’s professional position after 1840 would become a bit like Oxyaena’s in the Peabody mural. He, too, would find himself cornered by enemies, somewhat unjustly, because of his predatory nature. So it is ironic that the large herbivores cornering Oxyaena in the mural were among Owen’s greatest discoveries. ” 26 the origin of mammals Figure 5. Coryphodon and Oxyaena, with Pelycodus (Eocene) from Zallinger’s Age of Mammals mural.

These features suggested that it was much older than the Paris gypsum, and in fact it overlaid a stratum, called the oolite or “egg stone” because its texture resembles fish roe, that was known to be of mid-Secondary age. The Stonesfield “slate” yielded large saurian bones, and William Buckland, a geologist and custodian of the University’s Ashmolean Museum, had acquired many of those. Buckland, also canon of Christchurch College, was a vintage clergymannaturalist, a jocular eccentric who liked to serve dinner guests crocodile or ostrich meat and kept a menagerie that included a bear, which his son would dress in academic robes for garden parties.

The hind foot may have been split, two toes one way and then the others. I haven’t fully made it out yet. What if it climbed trees for its prey?
