Any critters that close to the impact just vaporized in the flash. And very unlikely that any ejecta reached escape velocity. The particles were small, hot, and those that got sucked up into the mushroom cloud (just like in a nuke test) didn’t travel in straight lines.
After all; Barringer - a LOT closer in time to the present; should have left SOME kind of ‘event’ marker other than that big hole in AZ.
