Re: Titanis walleri from Texas
Quoting Jeff Hecht <firstname.lastname@example.org>:
According to my notes, dating based on the uptake of rare-earth
elements (a new technique) was done on the Sante Fe River, Florida
and Texas sites. In both cases, the Titanis fossils were mingled with
fossils from both the Pliocene/early Pleistocene and the late
Pleistocene. In Santa Fe, FL, the rare-earth element signatures
matched those of 2 million year old mammal fossils. In Texas, the
rare-earth signatures matched those of Pliocene horse fossils. That
implies there is no evidence for late Pleistocene Titanis.
And therefore, I take it, that the _Titanis_ remains found mingled with
Pleistocene fossils were reworked?
