Now while on a photo search I find this very odd artifact from Texas found while a dam project threatened an archaeological site with flooding, and it is obviously some sort of large blunt-nosed seal looking like a walrus or an Elephant seal (the latter more likely because it has no tusks). The only "Known" seal from the area was the Caribbean monk seal, which is much the same bodily conformation as the common seal and looks nothing like this:nor yet are there supposed to be any sea lions or fur seals in the area. This object was found in a child's collection of odd stones and bric-a-brac, presumably dating to the 1700s in a Spanish plantation known to have existed in the area at one time, but there were older Indian artifacts found in the area and among the child's collection. So there is no direct dating but it scarcely matters-there were supposed to be no large seals in Texas at the time or for any postglacial phase before that, nor yet any way of explaining how the people there ever came to know of such things as large seals that looked like this.
More recently there have been photographs which resembled elephant seals in the Caribbean, and in White River, Arkansas (the latter according to Mackal)
