TMNH Posted May 28, 2013 Share Posted May 28, 2013 Wow this month's contest is a real feast for the eyes!!! Late Devonian: Super Rare partial Placoderm Skull ( Tentative) found May 20, 2013. Found in Shallows of Lake Huron ON Canada Kettle Point Formation IMGP4461a.JPG IMGP4461a.JPG IMGP4450a.JPG IMGP4451a.JPG PL It's going to be a tough vote for sure, but I have to comment on the local find...nice one! I sure didn't see anything like that when I visited Kettle Point last year! I hope it is a placoderm, that would be really cool! Link to comment Share on other sites More sharing options...
piranha Posted May 28, 2013 Share Posted May 28, 2013 Hi Gus, Although your photos are a bit fuzzy, the starfish is a very close match for Hudsonaster. Attached for comparison is H. wardi from the middle Devonian of the Mahantango Fm. The genus is recorded as early as the Ordovician so a lower Devonian find would fit very nicely. Hopefully with the specimen in hand you can confirm the plate characteristics are consistent with Hudsonaster. Congrats on a spectacular NY fossil starfish! Cramer, H.R.

FossilDAWG Posted May 28, 2013 Share Posted May 28, 2013 (edited) I'd like to see a more in focus photo as well. Although Hudsonaster came to mind, so did Devonaster (photo from Forum member Crinus' excellent web site).

Malcolmt Posted May 29, 2013 Share Posted May 29, 2013 (edited) I thought about not submitting this but a few others suggested that this was a worthy find that should make it into the fray. So after some deliberation I think that I need to submit this little gem as it is really a quite spectacular specimen. Overall, this is the best specimen that I have seen from this location. I have no hesitation is calling it Museum grade. It was collected on May 18th,2013 and has had not had any preparation. In fact the only thing that I intend to do with it is square up the two plates to leave a 2 to 3 inch margin on all sides of the fossil Eurypterus lacustrus Upper Silurian Williamsville A formation Stevensville , Ontario, Canada Size 172 mm tip of tail to tip of head (6.77 inches for the non metric folk) What you see in this picture is the positive and negative plate on the quarry floor, the one on the right is still in the floor the one on the left is the top plate where it was flipped over besides the bottom plate You can see a little bit more about the find in this post on the forum http://www.thefossilforum.com/index.php?/topic/37694-an-unseasonably-cold-wet-miserable-day/ For those of you in the NYPS or Dry Dredgers , I will have it with me along with other specimens when you come up for your collecting trip . I look forward to meeting up with many of you again in person. Edited June 10, 2013 by Cris Link to comment Share on other sites More sharing options...

mikeymig Posted May 29, 2013 Share Posted May 29, 2013 DEVONIAN COMMUNITY Found this seafloor slab on May 25th. and finished the prep on the 28th. of May. There are eight Eldredgeops on it as well as a large Gastropod (snail), Bryozoans, Crinoid plate/stem, Coral, and Brachiopod. When I found it all I saw was one trilobite and the rest came to light during the prep. Thanks for looking, good luck to all who entered, and happy collecting to all!

FossilForKids Posted May 30, 2013 Share Posted May 30, 2013 Well I haven't entered anything in years but I just finished prepping one of my finds from the Early Triassic Thaynes formation near Cowboy pass. It's both sides which is rare for a matrix piece. It was found May 17th and prepped May 29th. The one side the matrix is polished and on the other left natural.

pleecan Posted May 30, 2013 Share Posted May 30, 2013 (edited) Definitely Placoderm bone ... but which part? think it is the dorsal skull region ... awaiting for Dr. Bob Carr opinion.... PL Dr Sue Turner has seen pictures the placoderm bone and did not dispute the initial id .... Dr Joe Botting "Anyway, the placoderm - niiiiice... certainly looks good for a partial skull to me. " The other alternative it could be the dorsal head shield distal to skull of the placoderm possibly from a protitanichthys.

Although Hudsonaster came to mind, so did Devonaster (photo from Forum member Crinus' excellent web site). Don I'm not sure what happened to the photo, the original 2.9 Mb file is pretty sharp, I resized in photoshop, but I'll try to get a better example up for you to see. Thanks for the ID help, the closest I found was Dactyloides and that didn't look right. Is this better? I re-cropped the original photo. Link to comment Share on other sites More sharing options...
piranha Posted June 1, 2013 Share Posted June 1, 2013 Thanks Gus, the new photo is much better. Hudsonaster still appears to be a good match. Attached is a line drawing for additional comparison of plates. Link to comment Share on other sites More sharing options...
