    Hemipristis serra

    From the album: Miocene of Maryland

    Hemipristis serra Calvert Cliffs, Maryland
  2. This hemi’s shorter side is longer than 4 cm, about 1.6 inches. I think it might be longer than 2 inches if the other root lobe is still there, so I used the clay trying to figure out the original size of this tooth. The results is almost 2, but I’m not sure if I doing it right?

    A rare Saturday Hunt

    Went hunting with a friend yesterday on the Peace River. Saturday is unusual for me because of increased river traffic on the weekends. Since I can hunt any weekday, I tend to avoid weekends. We were prospecting, looking for gravel. As always interesting finds: Not too many , but interesting .. One location had agatized shell: I guess this might be the equivalent of a RucksPit Calcite Clam, but this half bivalve is pretty complete and clearly an oyster. I am not positive on the creation process but think I ought to name it a silicafied Oyster. I would like to find more of thi
  4. Hello, Here is what I think is a nice lot of Hemipristis serra teeth from Florida, which are about 2~2.5cm size. However I have no experience with shark teeth or teeth in general so I was wondering if these seem real, if there seems to be any restoration/reconstruction? I think most of these have nice serrations, but how is the quality of enamel and root preservation? Thanks.

    Small Lee Creek Shark Tooth

    I received some matrix from @sixgill pete a while back in a TFF auction and picked most of it a while back and ID'd the bulk of the teeth and other material. Lately I have been going back through some of my sharks teeth and looking more closely at items I was unsure of These three teeth are one such group out of this matrix. I have read Purdy et, al (2001) a bunch of times, looked at elasmo.com for hours on end, read dozens of threads on here and am still a bit confused/uncertain. So, I figured why no just ask and get several more opinions, I always appreciate what folks here have to offer

    The three teeth on the left show variations in teeth of the shark Hemipristis serra.

    Hemipristis serra (Agassiz 1840)

    From the album: Pisces

    19mm. "Snaggletooth" Lower sympheseal. Miocene Burdigalian. Oberemeeresmolasse Formation. From Billafingen, B.-W., Germany.
  10. 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!

    Hemipristis puzzle

    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 fro
  12. 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!!

    Shark Tooth ID - Florida

    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?

    Shark Tooth ID - Florida (Part 2)

    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???

    First Meg

    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 g

    Calvert County Trip

    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!

    Lower hemi or sand-tiger?

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

    STH fire zone hemi’s

    Hey, I was wondering if it’s possible to find fire zone hemi’s in STH, or not? TIA

    Some Hemis through the years I picked up online, from forum members and even found personally. Enjoy Aurora,n.c.
  20. 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

    A couple of nice teeth

    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 th

    From the album: Huge Big Brook Fossil Collection

    Mostly the crow shark teeth, goblin, mackeral were collected from big brook. Maybe some others but about 25% isnt big brook.
  23. 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, ri
