Auspex, this is the Fossil Forum and not the Numismatic Forum. We're looking at the fossil under the quarter. Let's stay focused here. :P

yes, some vicious clerk at a stop-n-rob convenience store sandbagged me by giving me a coin with a bear on it. the nerve.

I'll assume they put the bear on the quarter to alert people of what a Godless killing machine looks like so as to avoid one at all costs. Plus, I believe Steven Colbert also put the grizzly bear "on notice". Bears are the No. 1 threat to America due to the fact that they're after our honey and our women (as per Steven Colbert).

bmore -

i'm not sure of the age since it was in the surf. some of the gulf exposures in the area are pleistocene.

Looks somewhat whalish to me (as I stare at a 50 LB block containing 2 articulated whale verts in my office) - not much of that sort of thing in TX but the late Don O'Neill told me he used to find whale material in your area.

is this from a whale or what?

A vertebra from a small toothed whale wouldn't be much larger than the quarter. Thats either a seriously gigantic toothed whale (i.e. sperm whale) or far more likely from a baleen whale.

Don't get me wrong but I have seen baleen whale verts and they are usually stand 8inches or taller. So it still looks like a small toothed whale

Size doesn't define or discern between odontoceti and mysticeti. For example, there is a Mio-Pliocene baleen whale that I research called Herpetocetus, multiple species of which are represented in the Pliocene of the east coast. It and its relatives Piscobalaena and Nannocetus all have vertebrae that are inches wide - and these are relatively common mysticetes. Additionally, modern baleen whales such as the pygmy right whale (Caperea marginata) and the dwarf minke whale are both in a similar size range.

Additionally, sperm whales in the 20-30 foot range are known from the neogene of the east coast, and some of the extant, 60-70' sperm whale Physeter. Their vertebrae are bigger than most fossil baleen whale verts.

And again, if this were toothed whale, it would not qualify as a small vertebra. Many mio-pliocene (and extant) odontocetes (as adults) have vertebrae that are little more than an inch wide.

In summary, there is a huge size overlap between the two, such that size is 100% unreliable. Lastly, morphology is useless as well, as the vertebrae of mysticetes and odontocetes are nearly identical, and can't really be identified.

So... all you really can say in this case is 'cetacean'.

dang! i was readin' all that and thinkin', "man, this is gettin' good!" and i pretty much had decided that by the time i got to the end of the post, i was gonna know that critter's social security number and which squid bars it hung out at, and then, bam, he gets pronounced a cetacean.

oh, well, at least i know that one's not a cow that wandered too far out while moo-boarding...

thanks, boesse. it's good to have you sea-smart guys on the forum, because i figure if the briney deep can throw something up at me, i've got a chance at learning something about it around here.

now if i could just get the gulf to pull back about thirty miles to pleistocene levels, i could do some serious finding of stuff...

In all seriousness if there was a way to jam a cable in your ear and the other end in my ear and download all your knowledge on cetaceans i would be on the way to your house right now. Keep the knowledge coming!!
