Birthday Fossil Hunting trip to Ardennes (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last weekend I took a couple of days off work for my birthday and I decided to visit a fossil spot in the ardennes which was recently recommended to me because there was a chance to find fossils of primitive plants as well as devonian fish (which is one of my main interests within the hobby). The site is relatively close by as well which was a huge plus as it only took an hour to drive. The fossils in this location date back to the late Devonian, Famennian to be exact (372.2 million years ago to 358.9 million years ago) After searching for a 45 minutes we finally found the top spot with the right layer rich in plant material, here are some in situ pictures of the larger examples (which we didn't extract). If I am correct I believe these are the remains of Rhacophyton condrusorum which is a primitive species of fern if I remember reading once. We were also lucky to find some fossils of devonian fish, which was the main reason for our visit. A lovely small Lungfish (Dipnoi indet) tooth An imprint of a fish scale of bone While it was quite a cold day, it was sunny and we had a quiet afternoon at the spot where we could search in peace.

Hi guys! I was in the Warsaw Geological Museum and there I came across this specimen which reminded me of Tabulate coral, but it was signed as a "sponge"... The sponge from the "maastrichtian age", when Tabulata already was extinct. I couldn't be more confused. This one still looks like coral to me. What do you think?

Just a note that James Cullison's 1944 monograph on the rocks and fauna of the upper Lower Ordovician of Missouri and Arkansas is now freely available for download or perusal at https://archive.org/details/paper-cullison-1944-the-stratigraphy-of-some-lower-ordovician-formations-of-the This publication has always been devilishly tough to get a hold of. A nice systematic paleontology section deals with the many gastropods and other mollusks as well as the less diverse brachiopods, trilobites, and sponges. The monograph covers the following formations as currently accepted in Missouri: • Smithville Formation • Powell Formation • Cotter Formation • Jefferson City Formation Enjoy and share as you like. Full citation: J. S. Cullison, 1944: "The Stratigraphy Of Some Lower Ordovician Formations Of The Ozark Uplift."

While doing security rounds at work, I stumbled across a nice slab chocked full of brachiopods, tucked in dock-side rip-rap from Northern Michigan. It's pretty dark outside, so the pictures aren't the best, but I do see several types in it. Better pictures will follow once I get it home.

Illusory erect spines(?) on a Kimmswick receptaculitid
pefty posted a topic in General Fossil Discussion
UPDATE: These seem to just be weirdly incomplete cross-sections through ordinary cylindrical meroms. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ This weekend in the Kimmswick Limestone in eastern Missouri (Pike County) I saw plenty of receptaculitid algae, mostly of genus Fisherites. But one cross-section has a feature I've never seen before: a fringe of what look like erect spines on the external surface. Can someone point me to a reference for understanding this feature functionally and/or taxonomically? I've looked in the usual places but I don't seem to be finding anything about spines. (If I were a vertebrate paleontologist, I would be saying they were feathers and proclaiming receptaculitids' "Sinosauropteryx moment.") Thanks.

I took my wife out for a quiet weekend in San Saba, TX and vicinity to escape from work and busy city life. It was fun to visit the river, suspension bridges, and bump into a couple old Indian campsites denoted by snails, freshwater bivalves, and burned rock on the surface. But the first thing to really catch my eye there was the small fossil display in the historical museum at Mill Pond Park...one fossil in particular. This huge orthocone nautiloid was the highlight of the visit for me. It is said to be from western San Saba County, which has Ordovician through Pennsylvanian strata. There was no provenance, so I won’t get too far keying this one out. I’ll have to just appreciate it at face value for aesthetic appeal, and for it being the biggest orthocone I’ve ever seen from Texas.
