Phoenixflood Posted November 24, 2008 Share Posted November 24, 2008 I can not speak for him, but I am sure Martijn would be interested in that serrated giant thresher shark tooth and many other fossils you've found. He started a new thread about trading with people from this Mid-atlantic Calvert Cliffs region. That thresher is awesome, BTW! I just sent the one I have over to Martijn and got some great stuff from Holland and surrounding areas. He has nice echinoids and teeth. Which brings me to this point, which I may start up in another thread, is there anywhere arounf MD to find Echinoids? The soul of a Fossil Hunter is one that is seeking, always.

Auspex Posted November 24, 2008 Share Posted November 24, 2008 ...is there anywhere arounf MD to find Echinoids? I quote here from Calvert County Living, a flyer by Wallace L. Ashby: "Sea urchins were considered rather rare until 1938, when a pocket containing hundreds of individuals was found at Scientists' Cliffs in a sandy bed near the base of the Choptank Formation. Paleontologists of the U.S. National Museum placed a large block from this pocket on exhibit there, and another in the Chestnut Cabin Museum where it remains our prime exhibit. Similar colonies at the same level are exposed infrequently. Clean, well preserved sand dollars are found with these sea urchins but not in such profusion. Sand dollars also appear in other beds but these usually are broken and encrusted with barnacles and mollusks."

Pristiformes Posted November 24, 2008 Share Posted November 24, 2008 found these yesterday and the trip before. Boy is it getting cold out, well i guess thats why we will be going to florida for a week.nice serrated giant thrasher 2 peccary teeth( found one each trip) ok arrow head, not as nice as my first one but its a different shape I can't imagine how large that giant thresher had to have been. Modern threshers have such small jaws and teeth, the giant thresher, as a species, must have been the mackdaddy of threshers! Very nice find. I'd rather find one of those than a meg.

I couldn't tell you the bed they are found in but every 10-12 years or so a big pocket gets exposed. Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted November 24, 2008 Share Posted November 24, 2008 OK, you know my lack of tooth knowledge, but where are the serrations? cant get them to show up in the picture, they are there, its odd how the giants can range in how big the serrations are Link to comment Share on other sites More sharing options...

jbstedman Posted November 24, 2008 Share Posted November 24, 2008 OK, you know my lack of tooth knowledge, but where are the serrations? It's a great tooth. I looked it up in a couple of references. Given the size of the tooth bmorefossil found, I assume this is Alopias grandis (Giant Thresher). According to Cocke (Fossil Shark Teeth of the World), there is an "extremely rare" version of the Giant Thresher that is serrated, though, from the picture, this one doesn't look to be. Also, Kent (Fossil Sharks of the Chesapeake Bay Region) suggests that the Alopias grandis teeth in the Bay area are probably upper laterals of a Mako, Isurus hastalis. Edit: Just saw bmore's posting about serrations. Interesting. Besides fossils, I collect roadcuts, Stream beds, Winter beaches: Places of pilgrimage.

Guest bmorefossil Posted November 24, 2008 Share Posted November 24, 2008 Edit: Just saw bmore's posting about serrations. Interesting. yea here are a few examples of how the serrations on the teeth can look so different, the one we just found seems to be serrated half way down the blade. and they are very light serrations http://www.phatfossils.com/pics/Alopias%20...%20Grandis2.JPG http://www.phatfossils.com/pics/Alopias%20...s%20Grandis.JPG this is a weird tooth because it has slight serrations http://www.phatfossils.com/pics/Alopias%20...s%20Grandis.JPG http://www.phatfossils.com/pics/Alopias%20...s%20Grandis.JPG the serrations on the second tooth looks like the one we found Link to comment Share on other sites More sharing options...
Phoenixflood Posted November 24, 2008 Share Posted November 24, 2008 my giant thrashers are way to rare for me to be trading. Just a suggestion if you were looking for more diverse teeth. I do know the rarity because I traded one to him. But maybe you have something else he would want. You don't have to trade at all bud but it's good to have options.

The serrations are hard to reconcile with Kent's suggestion about hastalis. Also, when I replied to your posting, your text "the serrations on the second tooth looks like the one we found" showed up, but not when I just read your posting in the thread. Does your image at the bottom of your postings cover text? EDIT: Never mind, now it shows up. Weird. Besides fossils, I collect roadcuts, Stream beds, Winter beaches: Places of pilgrimage.
