<HTML>Carl, recent in geological history (shrug). A couple of clarifications on what you said.

That's the order Condylarthra (minor spelling error), which Artiodactylae and Cetaceae are members of.

The wolf-sized mesonychid (ungulate from the order Condylarthra) <i>Sinonyx</i>, c. 60 mya, is the earliest known ancestor of the whale.

Pakitecus is c. 52 mya.

Hope this makes it clearer for any readers.
