Shamalama Posted March 24, 2012 Share Posted March 24, 2012 While attending the Delaware Mineralogical Society's show a couple of weeks back I picked up some material from the Upper Devonian estuary deposits of Red Hill, PA. I've not collected at the site yet myself but plan to during the DVPS trip in April so I thought it would be good to familarize myself with some of the material that could be found. I got this huge fish scale (genera unknown): Another, smaller fish scale (genera unknown): I made a mosaic of this scale with my Zorb microscope/camera: And I also picked up a piece of rock with lots of debris in it including what looks like some teeth: close ups in the next post. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Shamalama Posted March 24, 2012 Author Share Posted March 24, 2012 Here are the closeup pics of the fish bits in the last rock. All are very small, with the possible bone being about 15mm and the teeth being about 7mm. Bone?

Fossils4U Posted March 27, 2012 Share Posted March 27, 2012 Nice Finds! Canot wait to see more! Link to comment Share on other sites More sharing options...
FossilDAWG Posted March 27, 2012 Share Posted March 27, 2012 Sweet! That scale is huge. Oh, and Dave, genera is plural, genus is singular. A single scale could only be from a genus, not multiple genera. Just FYI. Here's a good site for the geology, fauna, and flora of Red Hill. Apparently scales of the crossopterygian fish Hyneria lindae are common. Here are a couple of images from the web: Do you think it might fit your specimen? There are several other photos at that web site, you'll have to scroll down pretty far which may take a while, as you'll probably stop to look at all the beautiful Devonian fish (I sure did).

Shamalama Posted March 27, 2012 Author Share Posted March 27, 2012 Don, Ahhh.... genera>genus... Ok I get it now. I think your correct on the Hyneria ID for the larger scale. I found this page which has scales that seem to match the "fringe" on the one I have: http://fossils.valdosta.edu/fossil_pages/fossils_dev/f62.html. Both of the web sites you provided are wonderful time wasters too. I'd forgotten about that Devonian Times page but I have seen it before. Based on the pics from your second link I think the other scale I have is from an Osteolepid fish. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

squali Posted March 27, 2012 Share Posted March 27, 2012 Thanks for the post Dave. I'm trying to get my schedule straight to go on the field trip as well. It's always good for me to see what I'm looking for prior to collecting. It's hard to remember why you drained the swamp when your surrounded by alligators.

lagerstatten Posted May 2, 2012 Share Posted May 2, 2012 Beautiful specimens! I have seen some teeth from red hill that are jet black. Has anyone else seen this preservation before? Link to comment Share on other sites More sharing options...
