  1. Here is a photo 15 various Mako teeth I have collected at Calvert Cliffs. I have been sticking them in a baggy marked Makos, but now I want to display them with the correct labels. The Isurus vs. Cosmopolitodus hastalis thing is confusing for a newbie, as is correctly identifying Broad vs. Narrow vs. Longfin. (Are there others besides these three types Makos at Calvert?) Does anyone want to take a stab at identifying these, or tell me what features I should look for to differentiate them? Thanks!
  2. Can anyone help me identify this tooth? Found at Brownies Beach on the Chesapeake Bay. It looks similar to Makos, but I can't find any pictures of one this curved?

  4. A Short Trip ... to the Movie Theater ?

    Hello everyone .... sometimes shark teeth turn up in the most unusual places. My son and I went out for a movie at the local AMC theater in Savannah, GA to see Peter Rabbit. While we waited for our ride my son and I tooled around the parking lot picking up the usual suspects ... rocks and acorns oh my ! He commented about the large oyster shells in the mix and I said .. yeah, oyster shells can be pretty common and cheap, they dredge them up from the bottom of the ocean. Look, see these quartz pebbles they come from the same spot. Wait ----> is that a shark tooth ? Yep. Bleached by the sun .. staring right at me. All cleaned up ....
  5. The Great Cosmopolitodus

    I have some questions surrounding the extinct species of Giant White Shark, Cosmopolitodus hastalis. I think it was a fascinating creature, but for reason it doesn't seem to be brought up much. As far as I know, it was a very large shark that lived during the Miocene Epoch, and scientists believe it to be a possible ancestor to the extant Great White Shark, the biggest and meanest shark of our present day oceans. What I'd like to know is what was this shark really like? Did it look similar to the Great White? How do we think it behaved? How exactly does it fit into the lineage of the Great White? How big was it? Did it share the seas, or even possibly become prey for, the mighty O. megalodon? And finally, WHY do people call it "Mako" if it clearly isn't one?? Obviously, not all of these questions have concrete answers but I'd like to hear what you all know about the species. Google search results can only tell so much. Do you know of any good sources where I could read up about it in greater detail? I just think it's a really cool species, and I'd love to know more about it. Thanks!
  6. FL River Hunting Feb 22 2018

    Got in a few hours of digging today and popped a few keepers out. One day I'm going to find a nice complete Meg that size.
  7. Can't Mako Up My Mind

    This tooth was found along the base of the Calvert Cliffs in Maryland during one of my trips to Brownie's Beach. It made the Hop 5 of that trip because it's a decent size and cool-looking tooth, but now I've run into a problem. Of the few species of Mako shark found in the Cliffs, I don't know which one this is. I had it classified as an Isurus desori tooth in the Hop 5, but I'm beginning to reconsider that identification. After studying descriptions and pictures of specimen from both Cosmopolitodus hastalis and Isurus desori (supposedly the two most common Mako species in the area), I can't make a confident verdict. The tooth has a slant height of slightly over an inch, a thick root center, and broad crown with a smooth and defined cutting edge. It's size isn't much of a help because as far as I understand, C. hastalis is larger than I. desori but this tooth is right in between the average for the two species. It really could be either, but I'm sure there's got to be a good way to tell them apart that I'm just not aware of. The two sharks are really quite different after all. Although we hunters call them "Makos", C. hastalis was truly a Giant White Shark. Anyway, I'd love some help on this one. I'll attach a few pictures, including one with a scale, as well as the ones I posted in my Brownie's Beach trip report from 12/26/17. Thanks!
  8. Large shark tooth, Florida

    I found this bad boy today and wanted your opinion on it. I'm leaning Mako here, what do you think?
  9. So 2018 has been on a roller coaster of sorts. The east coast was hit with a prolonged cold snap to start the year which froze all the beaches up and most of the Chesapeake Bay too. So there was no hunting at all for the first week and a half of the year. The weather finally broke and i hit the beach i was luck enough to find a nice 2" meg/chub and the tripmaker was a pathological hubbell megalodon i was super stoked. Then the cold came back and once again the beaches froze right back up, so I was back off the beach again. The weather broke and all the ice went away and i hit the beach yesterday and killed it. Found the beautiful lower lateral meg that is just under 3.5", a couple nice makos, the 2 1/4' chub and a super sharp little meg. I also cleaned up on cetecean verts and chesapectens and an inner earbone it has been an up and down kind of month. Here is to a productive 2018. Hope everyone does well.
  10. After too many days of cold weather, we were determined to head out to the river during some spring time weather...we weren't prepared for what we found! Snow and ice was stacked up all over the place, for the most part I thought the trip was a bust but we decided to go for a hike anyway. After about a 1/4 mile, we saw some open water along the shore and headed for it...it wasn't much but we had about 600 yards of open beach and mostly open water...there was still some skim ice and slush but we at least could say that we were going to get to hunt a little. We weren't there 10 minutes until I heard a boat running around on the river, I thought to myself, "who is crazy enough to be out on the river with this much ice?" As I watched the boat, it turned and came towards me...yep, I knew who was as crazy as me to be out, it was @SailingAlongToo with some other legends out and about. Always a treat to run into him on the water and chatting a little bit, he was off acting as an ice breaker! LOL! After he left we got back to searching and lo and behold, we started to have some success. We were only wearing boots so I took the water since my boots are taller than my wife's, as I looked down I saw a beautiful site, a Mako! I have many that are much nicer than this one but this was my largest by far. A little while later I heard a squeal of delight from my wife, I looked back to see her holding up a small Meg. All-in all, it wasn't a huge haul today but it was nice to be out on the river again, I'm looing forward to when the ice melts away though I don't think it will be anytime soon. Working our way through the snow and ice. Something to search. My wife scores! Total haul Meg and Mako
  11. Some shark teeth ID

    Today, my package arrived. A pile of 1000 shark teeth have arrived and there are some Megalodon teeth and some Makos and Angustiden and some tiger shark teeth. But I have a few I am not sure about. Is this a Megalodon tooth? I have no information about where these are found but could this be a Angustiden or even a chubutensis?
  12. Calvert Cliffs Calendar

    So i mentioned I was going to do a Calvert Cliffs Annual calendar to highlight my best finds from each month. Well I took all the pics and sent it off to the printer they will be ready in a week. This way when i'm too old and senile to hunt anymore I will be able to flip through the old calendars to remember when things were found. So without further ado here is the first of many years to come!! JANUARY FEBRUARY MARCH APRIL MAY JUNE JULY AUGUST SEPTEMBER OCTOBER NOVEMBER DECEMBER COVER
  13. Calvert Cliffs

    I live in Dallas and usually hunt the NSR. However, I had some airline miles and decided to fly to the Chesapeake Bay for the weekend. I probably could have waited for a chance to spend more time there, but eventually convinced myself it was a great way to end the year and told myself that I would find a Mako and Megalodon tooth. If I could do that, the trip would be worth it. I only had 24 hours there, but made the most of it. I'm at the airport now heading home, figured I would post my finds. Thanks to @paxhunter for the advice he gave me.
  14. Hello everyone, I've had an idea for a while now to write and illustrate a guide on the fossil shark species of SC and how to find their remains. I really am not sure where I would like to begin, but my brainstorming process apparently involves a certain amount of doodling. These pages represent studies for how I might like certain parts of the guide to look, though all text will be typed in the final product. I am looking for any feedback - critique of the artwork, topics you'd like to see covered, additional information, etc., etc. enjoy! Here's a page that started for a mock-up for the specific species Hemipristis serra. I also drew a representation of Isurus desori on the bottom... A page dedicated to Carcharocles/Otodus megalodon (as I imagine him) And a portion of a simple tooth guide (not really sure how to incorporate this yet) - And thats most of what I've got so far. What do ya'll think?

  17. Realized this while talking to a buddy who doesn't know much about FL fossils, since (almost) everyone can agree Cosmopolitodus/Carcharodon hastalis was much more related (I mean ancestral) to the modern great white rather than modern mako's, shouldn't we be calling them "white sharks" instead of "mako's"? By not saying "great" imo you clearly don't mean Carcharodon carcharias & iirc paleontologists only though they were ancestors of modern mako's because they had no serrations.. sorry if this is a rhetorical question, but I couldn't hold it in any longer.
  18. Today's Massive Desori Mako!

    Hello Everyone! It's been a minute since I've had the pleasure of finding any fossils worth posting here, but I was lucky enough today to squeeze in a couple hours of hunting. I noticed several sets of footprints around my usual hunting site - others had picked through the material recently. Undeterred, I made my way along the river visually scouring every square inch of exposed grey-brown Oligocene formation and gravel. Im glad I stuck with it because I was rewarded with several nice (albeit small) teeth from the extinct mega-tooth white shark, Carcharocles angustidens as well as a slew of smaller teeth. Then, just as I was ready to start hiking back to the car, I noticed the root of a VERY large mako tooth sticking out of the ground. When I pulled it up I was reminded of the sword in the stone..it just kept going and going. At a little over 2.8" it's one of the largest Isurus desori teeth I've ever personally seen. It's in great condition with exceptional color to boot. Thanks for taking a look and as always... Happy hunting! SOSC
  19. C. hastalis

    This broad tooth mako (or broad tooth white shark) is near the max size for its species. It is a massive tooth, that at first glance when found, made me think it was a meg. But just for a moment. Most C. hastalis found are 2" or less. Whether you call this Carcharodon or Cosmopolitodus it is a desirable tooth and is currently thought to be the ancestor of the Great White Shark; Carcharodon carcharias.
  20. Well i went out on the Pax today and the mud that has been covering the beach from the high tides a couple weeks ago is finally almost gone. I got to look at some material that has been buried under all that mud and came away with a 2" mako that as you can see was trying its best to hide from me and a bunch of other teeth too all in all not a bad trip!
  21. Hello again! I was just wondering if this tooth is a Carcharodon Hastalis Tooth. I found it at Brownie’s Beach as I was combing the beach. Thanks for the help.
  22. I visited a quarry in eastern North Carolina today that is not often hunted. It contains early Oligocene River bend Formation, Pliocene Yorktown Formation and a pebble Pleistocene lag. I managed to find a few Oligocene echinoids (Rhyncholampas gouldi newbernensis) and another unidentified to this point, echinoid from the River Bend Formation. Pictures of these will have to come after they get cleaned up. From the Yorktown Formation I found this gorgeous 3 and 1/4 inch Carcharodon hastalis; finally making the coveted 3" club. This is it on the tailgate of my truck, will post more pics later. and from the Pleistocene pebble lag I found this gorgeous leg bone. Complete and in stunning condition. Not sure if it is horse? camel? bison? I will take more pics tommorow of the identifying areas and post it in the ID forum. There was also an amazing 5 x 5 meg found in the Yorktown by another hunter (and forum member) hopefully he will post it.
  23. Calvert cliffs 10/6/17

    So the water levels were the lowest they have been since April. I walked in the heavy cobble that hasnt been visible in months and came away with a pretty good haul. Then the waves picked up and took away the visibility bad not a bad day at Calvert Cliffs!
  24. These first two fossils I picked up while hiking mountains in the negev desert in Israel. I think one of them is a sea shell with a barnacle on it. I'm not sure about the other tubular one. The final one is what I believe is some sort of mako.
  25. Isurus

    From the album Mitchu Fossils

    Found a bunch of teeth from this site but this is the only one that had most of the root intact
