Evgeny Kotelevsky Posted November 18, 2013 Share Posted November 18, 2013 Hehehehe! This is my area of interest! I have near a thousand specimens from all over the world and always looking for more to add to my collection. I also have a remarkable collection of exetent porifera. Dr. Rigby and Bob Cooper both got me started in this area almost twenty years a go. Post some more pictures of what you got folks!

Wrangellian Posted November 19, 2013 Share Posted November 19, 2013 Fascinating, I would not have even recognized some of those as sponges! Shows you what I know. Did that Hindia just happen to split fortuitously on its own? Link to comment Share on other sites More sharing options...

docpaleo Posted November 19, 2013 Share Posted November 19, 2013 I under estimated the size of my collection by half. It appears to be well over two thousand specimens. I'm in the process of moving and the collection all boxed up is 4' X 4' by 30" tall, so about 36 square feet. Link to comment Share on other sites More sharing options...

Missourian Posted November 19, 2013 Share Posted November 19, 2013 Nice sponges, docpaleo. I under estimated the size of my collection by half. It appears to be well over two thousand specimens. I'm in the process of moving and the collection all boxed up is 4' X 4' by 30" tall, so about 36 square feet. Do you have any (unpacked) Pennsylvanian sponges to show us? Context is critical.

piranha Posted November 29, 2013 Share Posted November 29, 2013 Belemnospongia have long been considered holdfasts (Hinde, 1891) or root tufts, but the 2004 Treatise states: "its consistently circular outline and apparent lack of attachment to another part of a sponge suggest that it represents the entire sponge."

Missourian Posted January 29, 2014 Share Posted January 29, 2014 (edited) .. I am including some type of encrusting sponges that I found.. Pennsylvanian in age.. (Texas) My hunting buddy Lance and I find these in the Graham Formation.. Unknown at this time of exactly what they are.. 101_1886.JPG 100_1228-1.JPG I spotted something similar called Incrustospongia while browsing through the updated (2004) porifera volume of the 'Treatise on Invertebrate Paleontology'. I Googled it and found this: http://www.google.com/imgres?sa=X&rls=com.microsoft%3Aen-us%3AIE-SearchBox&biw=1065&bih=710&tbm=isch&tbnid=aKzN8kOpPqvZXM%3A&imgrefurl=http%3A%2F%2Farchives.datapages.com%2Fdata%2Fcspg_sp%2Fdata%2F017%2F017001%2Ffigs%2Fcspgsp0170967-fg2.htm&docid=QAKyeZX6OzRdtM&itg=1&imgurl=http%3A%2F%2Farchives.datapages.com%2Fdata%2Fcspg_sp%2Fdata%2F017%2F017001%2Ffigs%2Fcspgsp0170967-fg2.jpg&w=700&h=876&ei=z1_oUpXSIMrkyAHY8YDwBQ&zoom=1&iact=rc&dur=421&page=1&start=0&ndsp=19&ved=0CFQQrQMwAA Edited January 29, 2014 by Missourian Context is critical.

I sent a few pieces to an expert well over a year ago. He said he would look. I contacted him several months after mailing them and he hadn't had a chance to look. Out of curiosity I will followup..

erose Posted February 4, 2014 Share Posted February 4, 2014 (edited) Ok, that Jeffords paper shows the cup side of a "Palaeacis" coral (plate 1, fig 1a) BUT the backside (plate 1, fig 1b) of the coral looks nothing like the actual backside of a "Palaeacis" coral that is found commonly at Jacksboro and in the Texas Penn Fossil book. In fact the backside looks exactly like the encrusting organism (also figure 3) that we've found covering other stuff. Roz has posted 3 good examples and they are not even shaped like "Palaeacis" anyways under the surface. I think Jeffords has linked two fossils as one. MissCorals-mistake-redo.jpg Jeffords or whoever must have found a "Palaeacis" with the encrsuting thing on back and assumed it was part of it. I've seen one of the mystery things that look just like figure 1b where the edge (blue line) is raised forming an irregular shaped bowl except it was on the backside of a smooth shell. Roz also has an example of it wrapped around the core of horn coral. The question is still what the heck is it? So we now have an answer to what the heck are those encrusting things on our Pennsylvanian fossils. A friend shared a copy of the paper with me. A Late Pennsylvanian Encruster: Terminal Paleozoic Calcified Demosponge?, Ann Molineux, Pangea: Global Environments and Resources — Memoir 17, 1994, Pages 967-982, Biostratigraphy She has erected a new genus and species: Incrustospongia meandrica n. gen. and n. sp.. The family and order are Incertae sedis and the class is questionably Demospongia, but she is pretty sure these are sponges. They appear to range from late Desmoinesian to early Virgilian time. I know I have many from the Finis Shale (Virgilian) here in Texas. PS yes, it is encrusting the backs of the Paleacis sp. corals in that New Mexico paper… Edited February 6, 2014 by erose Link to comment Share on other sites More sharing options...

Tabfish Posted February 11, 2014 Share Posted February 11, 2014 Internal structure of a sponge from the Holderness coast, East Yorkshire. I found it in the surface of the boulder clay that makes up the Holderness coast, the next high tide would have destroyed the intricate rare trace fossil. The outside sponge is flint that has degraded and left behind the chalk infill. Tabfish Link to comment Share on other sites More sharing options...
LanceH Posted June 12, 2014 Share Posted June 12, 2014 Maybe somebody can identify these Pennsylvanian Period sponges me and Roz found in Wise county, Texas. I think the geologic unit is Devil's Den LS or there about. Some of these look a bit like like "Heliospongia" but not exactly. Can someone ID these or check the Treatise Part E Porifera? I've checked the 6 sources I have but no match I'm comfortable with. A B C Thanks! Link to comment Share on other sites More sharing options...
