Made my first fossil hunting trip to South Carolina, went to some areas around Summerville, thought I’d share pics of some of the fossils I collected! The best finds were some echovenator-like teeth, Angies, great whites, some intact sections of dugong ribs, and several associated pieces of a sea turtle shell. Felt like Indiana Jones exploring all the creeks trying to find productive spots haha. Fun trip, hope to return in the future!

Any thoughts appreciated on the following. I've been working with some material from the Old Church Formation, including previously undescribed sites. The following tooth is from that work. It has most of the characteristics of an early Hemipristis curvatus (Or Hemipristis serra, if you follow Muller). Muller reports two possible teeth that are close to this shape from the Old Church: early Hemipristis serra and Galeorhinus aff galeus. What follows are three photos. 1) The tooth I found and am hoping to identify, 2) a Hemipristis serra from Muller, 1999 and 3) a Galeorhinus aff galeus from Muller, 1999. I lean strongly towards H. serra, but the tooth lacks serrations on the mesial edge. This makes me think that it may be a very early transitional or that there are some positional distinctions that I've not picked up on. The root and distal edge are much more consistent with H. serra. 1) The tooth I found and am hoping to identify (scale box=5mm): 2) a Hemipristis serra from Muller, 1999 3) a Galeorhinus aff galeus from Muller, 1999 (teeth labelled 1a, 2 and 1b) Full citation for photos 2 and 3: Müller, A. (1999). Ichthyofaunen aus dem atlantischen Tertiär der USA. Institut für Geophysik und Geologie. @Gizmo

I went out on a fossil hunt last Thursday to one of the streams I like to hunt at. It was only around 28 degrees F when I arrived so I didn't have the highest hopes. I ended up having my best day both quality and quantity wise! I found my first New Jersey hemi as well as my first tiger shark tooth. Also found a really nice sized sand tiger as well as one that would have been a monster if it was whole. Hope you guys enjoy!!

Please help me ID these shark teeth that were found on the west coast of Florida (near Venice) over the past weekend. My belief is that the top row could be Great White and/or Megalodon (very nice serration on the largest/first one), the second row is either Bull or Dusky, and the third row is Hemipristis (Snaggletooth). As for the fourth row... the jury is still out. I am most intrigued by the third/tiny one (from left to right). It looks different from anything else I have ever found. Very compact, lots of detail, and oddly shaped. Any ideas???

Please help ID any of these sharks teeth that were collected from the west coast of Florida (near Venice) this past weekend. Based on my research, the top two rows look like Sand Tiger and the bottom two look like Lemon. Would this be correct or are there any that look out of sorts?

We recently were able to take a trip to the Miocene of Virginia along the Potomac River. We weren't sure what the conditions would be, as the last time we were here the tide was extremely high limiting the length of the beach and how much was accessible. When we got to the beach we could tell it would be a good day, the tide was pretty low with still a couple hours to go before low tide, and we could see long stretches of beach in both directions. As we walked I wasn't having to much luck, but my wife who trailed behind me was finding some good sized hastalis teeth that I had missed. Once we got to a better section of the beach with cobble and larger rocks, we really started to take our time searching. In about ankle deep water I looked down and spotted a 4 7/8 inch halved meg, I couldn't believe it! By far the biggest and most complete meg I had ever found up to this point (Previously have only found very worn bits and pieces of megs). We kept searching and stopped to talk for a bit and when I looked down I saw another very worn meg sticking almost fully out of some fallen clay matrix. We were both happy with the day so far! Between two partial megs and a good number of hemi's and nice hastalis, it was definitely one of our more productive days. We reached the end of the accessible beach and decided to head back. On the way back, I was searching up along the higher parts of the shore and saw a small clay block with some black sticking out and picked it up. Looking at it I thought it was just some lignite, but decided to look a bit closer. I picked at it a bit and it ended up being a meg! My first complete and whole meg, I was extremely happy with the find and could finally check that off my list. Overall, we couldn't have asked for a better day weather or finds wise. For teeth we ended up with a good haul of hastalis, hemis, two partial and one whole megs, and a retroflexus.The plate pictured has on it a whale vert, epiphysis, and various shark or fish verts,

Are these sans-tigers or Hemipristis? Found in the Calvert formation. Note the different numbers for different teeth.

Took a trip down to Calvert County this past weekend and did some searching around the Matoaka Cabins and just outside of Flag Ponds Park. Think I did pretty well for a two day search!

I Was Looking at Something Else! Calvert Cliffs 9/22
HemiHunter posted a topic in Fossil Hunting Trips
My daughter had off from "school" Wednesday, so we took advantage of the opportunity and perfect weather to hit the cliffs for a few hours. After several days of rough water and winds, the Bay was calm with a favorable tide and pretty empty of boat traffic as you'd expect on a weekday. Arriving around 11:00 a.m., still a few hours before low tide, we thought we had the place to ourselves. But we soon came across the fresh boot prints of another collector who had already been through looking for the low-hanging fruit at the high tide line. A little disappointed, but undeterred, we went about our searching business knowing we would just have to work a little bit harder. The receding tide was dropping off some decent hemis, here and there, with the occasional tiger thrown in, but nothing huge. Rolling over clay chunks finally paid off, though, with a beautiful mako (or c. hastalis?) which was pristine and looked like it just came out of the cliffs. As we continued on, we picked away here and there in the wash zone, but found nothing else remarkable. Kind of at the end of the beach, I told my daughter we needed to wade over to one last little area that is usually hard to get to, but where I've found a few great teeth before...- 14 replies

Mostly the crow shark teeth, goblin, mackeral were collected from big brook. Maybe some others but about 25% isnt big brook. -
I biked off to my favorite Miocene shark tooth site again this afternoon and when I got there there was already a family with 2 young children scratching and sieving away at it. A bit of conversation showed that they were pretty new to it, so I gave them a few tips and gave the kids all the small Carcharias ones I was finding. Eventually they said goodbye and trundled off down the path. It wasn't even a minute after they were gone that I suddenly found a good sized Galeocerdo aduncus, my largest one to date. A couple of pieces were broken off the edges, but I managed to find both of them in the sand and could glue them back on once I got home. Shortly after that, a Hemipristis serra anterior popped out, also in 2 pieces which I could also repair in the end. That was only the second one of this species which I have found there up to now. Needless to say, I was pretty happy to have found them both, despite having to glue them back together. There were also a nice little Carcarhinus priscus and a Carcharias acutissima to top things off. Here they are.

Got out with my kids to Calvert Cliffs over the weekend for some attempted crabbing, general beachcombing and fossil collecting. Water was pretty clear without a lot of wave action, so patience was required to find anything decent in all the sand. We also had to keep our eyes out for the abundant sea nettles that have come in. Anyway, we had good success, with a couple of really nice snaggleteeth I pulled out of the wash about 10 minutes and 10 feet apart (two of a kind!). I had just been talking to a couple of collectors right in that spot lamenting poor hunting that day--so right time, right place. One of my kids also grabbed a really nice croc tooth, but it has only the front half. The highlight for me, though, was "making my own luck." I was poking around a few clay balls in the surf, as I have read about here in FF, and came across one with a really nice shark vert coming out of it. It was quick work with my screwdriver to set it free--my biggest shark vert by far and in pristine condition. (It was worth getting nailed a little by a teensy sea nettle I spotted too late--distracted!) We were lucky that we dodged a wicked thunderstorm just before heading home, but it was really cool watching the whole thing far out over the bay. I also found a tiny tooth that I can't seem to ID, so if anybody can help, I'd appreciate it. The best finds are below (minus a big piece of whale vert I forgot to include). Enjoy the pix!

Too cold and rainy to fish (no speckled trout yet for me, just out of season rockfish, huge cow nosed rays, and stiffback perch). So went tooth hunting. Unfortunately the kids(?) had dug a giant hole in one of my favored spots, so I ended up hunting one of the kids' favored spots. A hard grayish blue clay area which is usually too hard and unproductive for me, but when walking past I saw a black shiny object glinting in the sun; looking closer I noticed a fine serrated edge and digging around it soon discovered just a shard from a megalodon (which I had never noticed in the creek before). Very disappointed of course that it wasn't whole, but the clay was softer than usual with all the rain so I was able to dig into the bank and did pretty well. Several hemi teetch and pieces (lots of busted stuff here) plus a few makos and lots of teeth that are not the usual sand tiger spikes. Not sure what they all are, but usually these are in the minority, today they were the main things I was finding. Generally these teeth were fewer than what i find in the sand and gravel, but bigger and heavier. The kids must have found some nice stuff here. A layer of giant tree oysters below and mostly scallops (pectans) above, some in better shape than the teeth. Having some issues with my scanner, but will post some of my more "normal" finds from last week as well if I can get the scanner going.

Extant Hemipristis elongata shark tooth from Atlantic ocean?
Dino9876 posted a topic in Questions & Answers
Hello, I have another tooth from my collection that I am not sure about. For me it first looked like a very clear case. The shape of the tooth clearly indicates the snaggletooth shark (Hemipristis elongata). I was 100% certain with the ID, the teeth are almost unmistakable. The only flaw: The tooth was found on the coastline of the Atlantic between Florida and Virginia (unfortunately I don't know the exact location). Over 10.000km far from the distribution area of this shark. My question to you: is my ID correct? And if so, how can something like this happen? I hope you can help me. The tooth measures 15mm in leght. Best regards from Germany and stay healthy in this time!

12mm. Burdigalian OMM Miocene Found at Billafingen, B.-W. -
I took another bike ride up to my favorite shark tooth site today and spent a couple of hours scratching at the outcrop with my trusty Swiss Army knife. Didn't do bad at all this time around and was particularly happy to have found my first Hemipristis serra tooth Hemipristis serra 12mm. Carcharias acutissima 15 & 25mm. Sea bream Sparus cinctus. The largest single tooth has a diameter of 7mm. and the partial plate is 16mm. long. Anybody have an idea what the following 2 teeth might be?

STH Shark Teeth for Non STH Shark Teeth
fossilsonwheels posted a topic in Member-to-Member Fossil Trades
We know that fossils are not the priority for people at the moment. They are not for us either but I have found a good amount of stress relief in going through a large donation we got. The material is all from STH and we have enough to make a trade. It was part of the donation actually. Extra fossils for sale or for trade to improve our collection. I would like to avoid sales or doing smaller trades just for shipping reasons so I decided to put the trade stuff out as one lot. Given the current state of the world, consider this a post corona virus trade offer. We would probably not ship for 2-4 weeks if not a bit longer so we would not expect immediate shipping. Nobody needs to risk a trip to the post office. I did however want to put it out there. I think a little engagement among fossil nerds may be a good thing at this time We tried to put together a pretty decent representation of the shark and ray fauna plus a variety of colors. Miocene Temblor Formation, Round Mountain Silt Member Kern County, California Carcharodon hastalis- 8 teeth, variety of positions, variety of colors, none bigger than 1.5" Cosmopolitodus planus- 8 teeth, upper and lower, beautiful color array Isurus desori- 1 tooth Hemiprisitis serra- 1 symphyseal tooth Hexanchus andersonii- one partial tooth (I think upper) Heterodontus- 1 lateral tooth Physogaleus- 4 teeth Galeocerdo- 3 teeth Carcharhinus- 3 teeth Squatina Squalus Galeorhinus Included but not pictured- a couple of Cetorhinus teeth and a Mustelus tooth. Various Batoid fossils. We are open to any shark tooth offers but we do have some specific needs/wants. I listed them below. GW teeth Squaliformes- any family except Squalus Orectolobiformes- Hemiscyllium, Rhincodon, Ginglymostoma (Eocene & Cretaceous) Otodus sokolovi Isurus oxyrinchus and retroflexus some specific Cretaceous material- Cardabiodontid, Squatina, Ginglymostoma, Cretorectolobus, Odontaspis, Cantioscyllium, Cretoxyrhina PM us if you have any questions, need to see additional pictures, or want to make an offer. -
Hi guys I was in a rush but can take better pics at a later time, so far my tentative IDs are hemipristis Serra and isurus praecursor for right and left of 1st pic but no idea on the others (maybe galeocerdo In the middle though) those id’s were all of the top of my head so no real idea

Hello, I saw this tooth for sale on the Internet. Unfortunately the photo was very bad, so I tried to creat a vector graphic. I'm not sure if the tooth belongs to a hemipristis or a blue shark. Can you help me with this? The tooth measures a little over 1cm to the tip and was found in Indonesia (Pacific ocean). Best regards from Germany!
