I have a coprolite that has me somewhat puzzled. It was found in a river in South Carolina and dates Miocene-Pliocene. I picked it up at the Tucson Gem Show because I thought it resembled some east coast coprolites with longitudinal striations/furrows/grooves that @MarcoSr posted a while back. Now that I've looked at it for a while and done a little prep work, I'm not so sure the grooves are sphincter related. There are intestinal muscle marks visible on one side, but they don't seem to match up with the grooves. The grooves were filled with sandstone/limestone. I left matrix in the deeper portions to preserve the integrity of the specimen. Across from the grooves are what look like puncture marks. My first thought was that they were clam borings. However, they do line up with the grooves in question. Now I'm wondering if these could be tooth marks as well. Under magnification, I noticed smaller tooth marks and an impression that I can't figure out. My imagination is now getting the best of me, and I'm seeing food chain activity. I'm seeing a big fish nabbing a small fish that was nabbing an invertebrate that was feasting on feces. Do you think the larger grooves and holes could be tooth marks? Does anyone have any idea what could have left the impression? The only thing I could think of is some sort of mollusk. Love your thoughts on this. @Carl

I thought I would bring in the forum on a difference of opinion among a few collectors. Attached are views of a specimen identified as a Metaxytherium tusk (late Miocene, Bone Valley Formation, unnamed phosphate mine, Polk County, Florida) by one experienced Florida collector and another collector familiar with a range of marine mammal fossils. Two other experienced Florida collectors leaned toward an ID of whale tooth. The specimen resembles one in Domning (1988: p. 409, fig. 7) which was identified as a Metaxytherium tusk. The specimen in question is straight like a tusk with an enamel-coated crown with a constriction toward the tip as in the figure. I've looked for a similar specimen labelled as a whale tooth in various publications (Richard Hulbert's "Fossil Vertebrates of Florida; the Lee Creek volume that covers mammals, etc.) but couldn't find one. Metaxytherium was a "sea cow" or dugong relative that lived during the Miocene - a time when sea cows were more diverse and widespread than they are today. The Florida collector who thought it was a Metaxytherium tusk pointed out the enamel texture and its laterally-compressed overall form was the same as a tusk. The other Florida collectors didn't point out any particular feature to count it out as a Metaxytherium tusk - just didn't look right to them. I can understand having difficulty articulating an overall impression. Those two guys know Florida fossils so I respect their opinions. I'm interested in reading what other collectors think - especially all the Florida/Bone Valley collectors out there. I'll try to get a scan of the figure in the Domning article and attach it - couldn't find a pdf in a quick search. Thanks, Jess Domning, D. P. 1988. Fossil Sirenia of the West Atlantic and Caribbean region. I. Metaxytherium floridanum Hay, 1922. Journal of Vertebrate Paleontology 8:395–426.

Hi all, I have been having trouble finding a good guide to use in order to ID fossil seashells (mainly gastropods and bivalves) of the Neogene-Quaternary of Western Europe (mainly Belgium/Netherlands). So, I'm turning to you guys: does anyone of you have a nice up-to-date website/online paper that I could use in order to help me ID all of my different seashells? Preferable with clear photos/drawings of the different species. Thanks in advance! Max

Hey everybody! It’s been a handful of years since I posted on here, but I was in Capitola recently and I picked up this fossil. The low tide wasn’t very low that day, (3.7 I think?) so...not the best day for collecting, but I drove in from AZ so I went anyway. On my way back to the car (giant toddler in one arm, heavy bag of fossils/shells/rocks in the other, I tripped over this guy. I didn’t get a chance to really look at it but It looked like it might have had bone in it so I threw it in the bag thinking maybe it was a partial vert or something. But now that I’m home and unpacked and have had a chance to actually look at it, it seems like it might be some part of a skull? Does that seem right? (Can you tell I mostly stick to invertebrates? Ha!) Also, sorry if this picture ends up being huge this is my first time posting from my phone and I can’t figure out how to change the size. It will only let me attach one photo, so I’m assuming the size is the issue. thanks in advance for your help! Edited to add Capitola makes this Purisima Formation, Neogene Period so Miocene/Pliocene. Marine fossils. (Forgot all the important information!)

Here are a great white (Carcharodon carcharias) and an Aetobatus tooth from a site other than the main one(s) around Sacaco from which we have seen teeth (or perhaps an example of what was found on the surface). This Aetobatus tooth might be the coolest-looking one I have - rather large with deep color and some apparent microfossils embedded within the patch of attached matrix. I am starting this thread because there was a question in another thread about the range of preservation seen in fossils from the Pisco Formation, Sacaco area, Peru. We tend to see mostly lighter-colored (blue or pink or blue and pink), well-preserved great white teeth with great serrations but there were also some teeth on the market that were more worn and duller in color yet shiny from that wear. They appear to be more mineralized too. If you have similar Peruvian shark teeth, feel free to post your photos. You can't get them anymore but we can look at some of what was allowed to go before the export ban. I tried to pick up the widest variety of fossils while available. Jess

Come see our booth at the Aurora Fossil Festival!
Boesse posted a topic in General Fossil Discussion
Hey all - our collections manager and I busted our tails off yesterday trying to get everything ready for the Aurora Fossil Festival on Saturday in Aurora, NC. We're going to have a table for the Mace Brown Museum of Natural History (CCNHM), our museum at College of Charleston. We've got some neat casts on display as well as a couple of cases - one is a case chock full of fossils from Folly Beach, SC, and the other is a case full of Miocene and Pliocene odontocete ear bones from the Lee Creek Mine. If you're attending, be sure to bring marine mammal fossils with you for identification - or just to show off and make us jealous! We'll be in the community center sandwiched between tables for the Smithsonian and the North Carolina Fossil Club. We're looking forward to seeing you there! Lastly, we're also looking for marine mammal fossils from Belgrade Quarry to add to our collections as part of ongoing study of Oligocene marine mammals from the southeastern USA. Teeth, earbones, and skull fragments are not common at Belgrade but several critical specimens have already been donated. With a few more specimens, I will be able to put together a paper on the marine mammal fauna of the Belgrade Formation. Hope to see you there!

The Corossol Impact Structure, Gulf of St Lawrence, eastern Canada

This tooth was collected in the Sharktooth Hill Bonebed by Bob Ernst back around 1994-1995. At the time he and I thought it was a weird Parotodus because it appears to have a bourlette. The form wasn't really a good match otherwise. It's just over 1 7/8 inches along the slant and about 3/8 inches in labiolingual thickness. The cutting edges are underrated with no hint of lateral cusplets The tip is chipped but it doesn't appear to have been damaged when it was collected. Now, I think it's the giant thresher, Alopias grandis, but seems irregular for that as it basal outline of the root isn't a broader U-shape - maybe a jaw position variation or a regional variation. The apparent bourlette could be just the way some of the enameloid wore off. I don't think I've seen another tooth like this one from the STH Bonebed - thought the forum might want to see something oddball. I was inspired by that weird spiny thing that Marco posted a photo of. Jess

Temporary Carcharocles Megalodon Exhibit At The Flmnh
siteseer posted a topic in General Fossil Discussion
I was in Florida on business last week and visited the Florida Museum of Natural History over the weekend. Museum workers were setting up an exhibit starring the big shark. You could see the first and last part of the exhibit from the hall. I was told there was a megalodon exhibit in 2008 or 2009. I missed that one and maybe this one too as it opens next weekend (October 4) and runs until early January. The good news is that the museum store was already selling souvenirs for the show. I bought some t-shirts for the family and a few refrigerator magnets. They were giving out bookmarks and card-like flyers for free. Here's a link to the museum announcement: http://www.flmnh.ufl.edu/exhibits/coming-soon/megalodon/ Some fossils from Panama, including megalodon teeth, were already on display in the hall but that is also a temporary exhibit. It's a great museum overall. I visit it whenever I'm in the area.
