These are all over our desert property in southeastern Cali. Various shapes, sizes, textures, and colors but I grouped some similarly textured ones for this photo. The ones pictured in the group are all lightweight with the texture of coral but we have many others with the same shapes & paisley-like designs (hard to see in photos) but made of smoother rock. I thought for a long time the pink thing in the last set of photos was someone's old spilled paint. It's about 12" wide. Any ideas?

Has anyone visited Mazourka Canyon Road East of Independence? YouTube videos in the last year show a reasonable road and Donald Kenney [http://donaldkenney.x10.mx/SITES/CAMAZOURKA/CAMAZOURKA.HTM] lists a number of sites and the possible fossils. BFLADY

Hi All! Some of you know me already, and I've been occasionally browsing the forum for years. I saw a couple of recent-ish threads that I wanted to comment on, so thought I should sign up at last... For those who don't know me, I'm a semi-independent researcher with honorary positions in Nanjing and Cardiff, while living for most of the year in the middle of nowhere (the wonderful little town of Llandrindod, central Wales). My main interests are the early evolution of sponges, worms, and early Palaeozoic ecology, but I basically like really old dead stuff, and the weirder the better. I've worked on a wide range of Lagerstatten, including the Hetang, Burgess Shale, Sirius Passet, Afon Gam, Fezouata, Llanfallteg, Llandegley Rocks, Llanfawr, and Anji biotas, so I tend to get around a bit when time and energy permit. I'm an old-fashioned palaeontologist, though, and am adamantly against the view that we now know the fossil record well enough to start concentrating on number-crunching. Everything I see on fieldwork suggests that, at least in the Ordovician, we don't yet understand even the basic diversity. That might possibly be correlated to studying a group that preserves largely as enigmatic blobs that everyone else ignores, but hey - it's a niche! The moral is, though, that amateur palaeontologists are increasingly vital in keeping the new finds pouring in. There's a vast amount out there left to discover. I'm not necessarily going to be able to keep up with everything on here, so please feel free to nudge me towards particular threads if you'd like my input! Looking forward to getting stuck in!

Most come from Illinois, and are as I figure corals and spines; question is what kind, and which? I apologize in advance, but instead of posting 20 threads for each one, I’m going to spam this one with all my sponge, coral, etc inquiries. So please be patient! (Thanks again guys for all your help! I only post the ones I cannot 100% identify via books and internet; unfortunately I gotta snarge ton more yet to come.) Here are items #1-3...

Lack of snow cover and warmer than average temps allowed me to explore and collect sponges and corals from the Pennsylvanian Naco Formation in central Arizona, north of Payson. Widespread chert of the Beta Member suggests that silicious sponges may have been common. Several have been identified but many more exist. I have seen and collected several undescribed species. Dilliard and Rigby have described several sponges including Chaunactis olsoni which I found in the area: The New Demosponges, Chaunactis olsoni and. Haplistion nacoense, and Associated Sponges from the. Pennsylvanian Naco Formation, Central Arizona. by DILLIARD and RIGBY http://geology.byu.edu/Home/sites/default/files/geo_stud_vol_46_dilliard_rigby.pdf EDIT: geo_stud_vol_46_dilliard_rigby.pdf Photo 1a.

Lately if you have seen some of the topics I've started, these trips revolve around an Ordovician reef I came across by the Credit River in Mississauga, Ontario. One of the few things I discovered while exploring these spots is that there are plenty of Stromatocerium sponges which I red is a stromatoporoid. My question is, can anyone lead me to any papers about the growth forms of Ordovician stromatoporoids? I have found specimens of stromatoporoids and from the way I see it, some of the specimens I found of the same species have different growth forms. Some have those things they call monticules on the surface, and some don't exhibit them at all. Instead these specimens exhibit cracks and splits on the surface of the organism with irregular bumps and overgrowths. I'd like to know what causes this. Some of these sponges, from what I have collected, colonize some pieces of Prismostylus on the top.

Hi all, I'm fairly new to this forum and fossil hunting in general. I need help identifying these, idk if they are coral, sponges, posibally bone or what. These were found in NE Kansas, in a rock deposit full of bryzoans, bivalves and other oceanic fossils. I do know the majority of these fossils here come from around the Cambrian through the Permian periods, however there have also been a few ice age fossils in the area, so that may help. Thanks a lot!
