gieserguy Posted January 22, 2020 Share Posted January 22, 2020 Date of Discovery: January 7, 2020 Name: Composita subtilita with naturally exposed brachidium Geological Age: Middle Pennsylvanian (~309 mya) Geological Formation: Naco Formation Location Found: Paleo Site near Kohls Ranch, Arizona, USA Thank you to @Petalodus12 and @DPS Ammonite for helping ID the exposed brachidium. The brachidium is a spring-shaped structure that supports the lophophore, the feeding organ that uses water to carry food towards the animal’s mouth! 10 Link to comment Share on other sites More sharing options...
digit Posted January 23, 2020 Author Share Posted January 23, 2020 Here's something a bit novel to broaden the entries for the vertebrate category for this month. Date of Discovery: 2020-01-21 Name: Giant Manta (Mobula [Manta] birostris) vestigial tooth Geological Age: Plio/Pleistocene? Geological Formation: Tamiami Formation? Location Found: "Cookiecutter Creek" Florida For the last several years I have been picking through micro-matrix collected from the small waterway in Florida known for the presence of Cookiecutter Shark (Isistius triangulus) teeth. There are several additional novel taxa found in this locality that are so rare as to make Cookiecutter teeth seem relatively abundant. The material is collected from float material in the creek bed and so the formation is presently uncertain but the interesting chondrichthyan teeth fossils seem to originate from a phosphate rich clay layer below a shelly layer which may be either Caloosahatchee Formation (2.5-1.8 Ma) or possibly Fort Thompson (140-120 Ka). The exact age is uncertain at the moment but additional investigation may soon assign a more precise date to these fossils. There are several unusual taxa that I've found in this little creek which are presently unknown in the Florida fossil record. The vestigial teeth of the Giant Manta (a filter feeding planktivore) are tiny cylindrical teeth with bulbous roots and enamel covering only the 'chisel' tip of the tooth. This particular specimen is just under 2.5 mm in overall length and shows very unusual coloration for fossils from this locality. The dentine base of the tooth (including the nicely preserved tri-lobed bulbous root) is a very nice tan color while the enamel cap is distinctly black due to phosphatic staining during preservation. This is an unusual tooth from a species that is not often seen in the fossil record (and is presently unrecorded from Florida). The really nice preservation and unusual coloration motivated me to submit this item for this month's gallery of finds. Cheers. -Ken 12 Link to comment Share on other sites More sharing options...
Max-fossils Posted January 23, 2020 Share Posted January 23, 2020 @digit while not being the most impressive fossil to look at, hearing its 'value' makes it clear as to why this is an amazing find!

digit Posted January 23, 2020 Author Share Posted January 23, 2020 Sometimes good things come in small packages. This species is in league with the Basking Shark teeth found at Sharktooth Hill or the Whale Shark teeth sometimes found in Aurora, NC. They are tiny non-functional (vestigial) teeth that are no longer of any great use to the organisms which now feed by straining plankton from the water. I have also come across a few even tinier teeth from the Lesser Devil Ray (Mobula hypostoma) but it has been a few months since spotting a nice specimen from that species. At less than 1/10" it would not be a "showy" specimen compared to a large megalodon tooth. In fact, it is difficult to even see or appreciate the detail without magnification. Still, it is quite the novelty. I likely have the most extensive Mobula fossil collection of anyone in Florida. I enjoy my tiny treasures. Hoping some nice vertebrate entries show up in the next week to knock this out of the running for VFOTM. I felt compelled to enter this little tooth as this contest is always a great gallery of what our members find (or prep) each month and I love the diversity of the finds (and localities). This is a novelty that I thought our members would enjoy seeing. Cheers. -Ken 9 Link to comment Share on other sites More sharing options...

Cheers. -Ken I definitely understand and relate to what you just said! in fact, the most important fossils are often not very impressive to look at. Being a shell-dude, I can definitely confirm you're correct. Some of my rarest fossil shells in my collection are very unimpressive, even when compared to other fossil shells. The famous quote for books applies to fossils too: don't judge a fossil by its appearance! Sorry if I made it appear that I was unimpressed by your find, it's the other way around. My previous comment was made to say just the opposite (mainly as a reminder to others browsing the thread) that an amazing fossil find isn't always very good at showing its 'amazingness' (so essentially what you just said in much better words) Max Derème "I feel an echo of the lightning each time I find a fossil.

My previous comment was made to say just the opposite (mainly as a reminder to others browsing the thread) that an amazing fossil find isn't always very good at showing its 'amazingness' (so essentially what you just said in much better words) Not a problem. It is the kind of fossil that lacks the geometric beauty of an ammonite, the detail of a Green River fish, the bulk of a megalodon tooth, and the awe of a mounted dinosaur specimen. If it were in a museum display (even under magnification) few would stop long enough to read the accompanying text description. I enjoy finding showy fossils as much as the next collector but for the research I'm doing into Florida's micro-chondrichthyan fauna, pretty (but minuscule) specimens like this make my day. While I don't often succeed in "much better words", I never fail in my efforts to provide "much MORE words". Still about a week left to round out this month's entries. Let's see what ya got.
