Nimravis Posted May 19, 2018 Share Posted May 19, 2018 I cracked this Mazon Creek concretion open today, and I am thinking that it is a Euproops danae Horseshoe crab, but not positive on this one. What do other members think? @RCFossils 3 Link to comment Share on other sites More sharing options...
Bone guy Posted May 19, 2018 Share Posted May 19, 2018 It looks like a horseshoe crab. The last picture of the negative impression is covered in bumps which is a crabby thing. 1 Link to comment Share on other sites More sharing options...
fossilcrazy Posted May 19, 2018 Share Posted May 19, 2018 Hi Nimravis, Looks like you have a Euproops to me. Nice score. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted May 19, 2018 Share Posted May 19, 2018 Yup. Compare to this : I think what you can see in your specimen is the head-shield and the uppermost part of the thorax. More to be uncovered, one suspects. Great find! Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I have a few, but this one looked a little funky. BTW- this concretion came out of Pit 4. 1 Link to comment Share on other sites More sharing options...
Bone guy Posted May 20, 2018 Share Posted May 20, 2018 Side note: euproops is one of the best names in the animal kingdom. 2 Link to comment Share on other sites More sharing options...
RCFossils Posted May 20, 2018 Share Posted May 20, 2018 Agreed It is definitely Euproops danae. Nice find from Shadow Lakes! Link to comment Share on other sites More sharing options...

There also is a Haug and Rötzer (2018) paper, which deals with Euproops danae and concludes that species-level classification is presently uncertain, given the lack of ontogenic sequences for other species, such as Euproops rotondus.
