Plantguy Posted December 9, 2009 Share Posted December 9, 2009 Yep PL, that's a really sweet little one. Very nice! I've never been fortunate enough to have ever found one but here's an incomplete head with partial flippers from New York that I got from somewhere/somebody for $12--no other provenance info. Is it possible to ID down to Genus from something this incomplete? Regards, Chris Link to comment Share on other sites More sharing options...

Is it possible to ID down to Genus from something this incomplete? Regards, Chris There's a quarry in Herkimer County, NY which is said to be nearly exhausted (Fiddlers Green Fm.). As far as I know, it's the main site for eurypterids in the region. Nearly all the eurypterids known from there belong to the species Eurypterus remipes. Yours has a head shaped just like the others I've seen but you'd have to ask a sea scorpion fan. Collectors of the quarry have identified pieces of a much bigger genus as well. Sometimes plant fossils are found with the prized find being an actual primitive scorpion (eurypterids weren't true scorpions - relatives in that both groups are arthropods) Link to comment Share on other sites More sharing options...
Terry Dactyll Posted December 9, 2009 Share Posted December 9, 2009 Pleecan..... What a strange looking creature, and a nice fossil....I can see why your attracted to these I like it.... is there anything comparable to it alive today?, it also looks very 'shrimp or lobster like'....

I believe that the fossil could be Eurypterus remipes (more probable) or Eurypterus lacustria.... I do not have the expertise to differentiate.... still learning.

Hi Terry: The Eurpterids are related to shrimps / lobsters.... probably very tasty roasted with garlic butter known to grow 2.5 metres.... As Siteseer has eluded to ...these evolve to terrestrial land scorpions... I will post some pictures of Eurypterids with their stinger assembly later on.

Bear Posted December 9, 2009 Share Posted December 9, 2009 I have a specimen from that Herkemer quarry, I'll see if I can't get a shot of it later. The telon is present and intact. Link to comment Share on other sites More sharing options...

erose Posted December 9, 2009 Share Posted December 9, 2009 Here is a link to Lang's Quarry near Passage Gulf, Herkimer County.: http://www.langsfossils.com/quarry.htm I have never been there myself but I know others who have. Allan doesn't often let folks in. It is really hard rock and you work like crazy and maybe find something good and then he sells it to you at a discount. But when you see what the big prepped ones go for even with the discount they ain't cheap. Apparently he has to expose and bust up lots of material, let it weather a number of years and then only can you start whacking at it with a sledge, hoping the conchodial fractures reveal a specimen. Some of the earliest scorpions come from here. There is supposedly a road cut in the area that on rare occasion offers up a specimen. The collecting further west near buffalo and into Ontario is supposed to be much easier. I have to dig out a few Eurypterid larvae I collected from black shales in the Shawangunk Formation Tiny little carbon smears, but eurypterids. Hopefully they will photograph.

Phoenixflood Posted December 9, 2009 Share Posted December 9, 2009 Awesome fossils all! Sea scorpians are another one I'd like to add to my hunting list. Does anyone have any fossils of brontoscopio?

Pterygotus are super rare prize... I have only see a stinger assembly once at Fort Erie ON! Great find!!! PL Link to comment Share on other sites More sharing options...
Auspex Posted December 9, 2009 Share Posted December 9, 2009 Were Pterygotus fully aquatic, or did they spend some time on land? Also, I assume that the stinger is an adaptation of the telson; is this the earliest hint of that change in arsenal?

Nicholas Posted December 9, 2009 Share Posted December 9, 2009 I've always found them odd looking critters, I had the chance to buy a nice one once but I thought it looked fake.. but turned out to be authentic. Great specimens everyone. Link to comment Share on other sites More sharing options...
crinus Posted December 9, 2009 Share Posted December 9, 2009 Here are a couple of specimen from my collection. This first one is from the Fort Erie quarry. Same quarry that plee collects. It is possible to find complete specimens in this quarry. This second photo shows the positive and negative of the same specimen. If you fine one you really find two. When purchasing eurypterids one needs to be careful. The positive and negative are usually sold as separate specimens. You rarely see them for sale as a pair. There is a difference. The positive has some three dimensionality to it. The negative is just a film (no pun intended). Finally my specimen form Herkimer, New York. This was found long before the Lang quarry.

Forgive me for the elementary questions, I'm getting caught up on a 50-yr-old fascination Hello Auspex: Great to ask questions... No need for apologies... I am the newbie instead... you have a great wealth of fossil knowledge to offer. Also Forgive me for my inexact use of words... " stinger" was ment to be Telson which is more proper term descriptor... often I equate present day equivalents to help describe a fossil that is less familar me in lay man terms. Pterygotus are marine aquatic, ... inhabited Upper silurian and highly prized to collect. The photo is close up of Eurpyterid remipes lacustris telson from Bertie formation. Long and pointed approx 1.5" in this case. PL Link to comment Share on other sites More sharing options...
Auspex Posted December 10, 2009 Share Posted December 10, 2009 Thanks! I thought that, since somewhere along the line they colonized land, and are at least related to scorpions, they might have actually been found with scorpion-like stingers.

pleecan Posted December 11, 2009 Author Share Posted December 11, 2009 Lets have some fun.... The fossil is a bit dusty from sitting on the self... Can you guess or know what Eurypterid Part this belongs to.... ? The fossil is from the Silurian period from Bertie formation... what is it?..... I will tell you the answer tomorrow if no one gets it. PL Link to comment Share on other sites More sharing options...
