Jurassic bird

A comment by Marx (Science, 199: 284) in 1978 mentions the possible finding
part of of a possible bird humerus from Upper Jurassic the the Dry Mesa
area, found by Jensen and looked at by Ostrom.  Does anyone know what
happened to this bone? Was it from a bird, Was it from a pterosaur? Or is
it still indeterminate. There was, apparently, no follow-up to this report
in the literature.

Many say it was a mistake to come down from the trees, some say
the move out of the oceans was a bad idea. Me, I say the stiffening
of the notochord in the Cambrian was where it all went wrong,
it was all downhill from there.
