verydeadthings Posted November 13, 2018 Share Posted November 13, 2018 Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella? Link to comment Share on other sites More sharing options...

verydeadthings Posted November 13, 2018 Author Share Posted November 13, 2018 This last one should wrap it up...I don't have a good guess about the genus but it looks spongy to me Link to comment Share on other sites More sharing options...

piranha Posted November 13, 2018 Share Posted November 13, 2018 You are on the right track using this publication, I presume: Rigby, J.K., Senowbari-Daryan, B., & Liu, H. 1998 Sponges of the Permian Upper Capitan Limestone Guadalupe Mountains, New Mexico and Texas. Brigham Young University Geology Studies, 43:19-117 PDF LINK If you search the references there are a bunch of papers on this topic from Rigby, Finks, etc. 1 Link to comment Share on other sites More sharing options...
verydeadthings Posted November 14, 2018 Author Share Posted November 14, 2018 Thanks for the link to the publication, Piranha, I hadn't actually seen that one! I think it will be quite helpful. Link to comment Share on other sites More sharing options...
