So I've been looking around at the pile in the garage, trying to get rid of some of the junk and taking some photos that I thought you all might be interested in. I think some of you may have picked on my fascination with earbones...If you dont have that fascination keep scrolling....Well, here's one partial example with multiple views that was a little more different than most but I think its a whale bulla. Its preservation is a little different and there is an extra cavity where normally you would have solid bone...just my guess anyways. Also another shot of it on the very left showing some of the other bullas and its relative difference. Maybe its something completely different. Here's a neat little blob of casts of sponge borings and I've been trying to get a real sharp close up of what I think is a bryozoan in the same matrix but its the best I can do. The unknown is really cool but I just cant capture the real coolness with my cell phone..The scaley looking fragment is approximately 6mm long.The preservation detail is remarkable given its only a fragment. I suppose I really should put this in the ID section as I was wondering if these are all same Sconsia species. S. hodgii? Not that important...Didnt realize I had 4 of them until recently. A couple of them have taller spires and I just cant decide if they are all the same or not. Here's a Chesapecten. C madisonius I think. (photos of after and before) that I put in 2-3 hrs here and there trying to clean. Was using dental picks and a brass brush to remove the sandy matrix and endless soaking. I could do more I suppose but I dont have the patience for prepping. I had ideas of separating the valves but maybe in another lifetime. It has all kinds of very small sponge boring holes and grooves that make me absolute crazy. LOL. Was hoping to find that it had attached barnacles but they were gone and I only had scars left. Those of you who have that patience to prep I applaud you! Lastly for all you barnacle and brach fans...I know there are thousands of you..I am one..LOL. So a complete brach Discinisca lugrubris around here is pretty rare. I only have a few and this is the 2nd of 2 brach/barnacle associations I have. What makes this barnacle on top of a brach extra special special was that when I recently was looking for plates/stuff inside the barnacle (which had no plates and mostly just sand) I found another brach...a tiny juvenile! Yeah! So its time for breakfast...Continued hunting success! Regards, Chris
TqB posted a topic in Fossil IDFound this piece of large (for the location) orthocone yesterday in a Brigantian (Mississippian) mudstone. The thin bits of surviving shell are apparently pierced through with many small round objects, mostly circular, 0.3 - 0.5 mm in diameter. Each one is now a very low cylinder (like a watch battery) with apparently vertical sides and depressed centre. Many are filled with pyrite. They have left impressions on the mudstone internal mould - the whole shell fossil is covered with them, both the living chamber and chambered phragmocone. Ostracods came to mind but these seem to go right through the shell and the spacing is quite regular so was whatever they were growing there? Orthocones and many other types of shell are common from this location but I've never seen this before. And one more:
