This website looks too professional for me. I single handedly picked up nice specimens back in 2004-2007. I would like to post pics but since I am new to forum , I can not. Do you not realize some of the best fossils are picked up by layman ? At any rate my specimens have been hidden away for the last 10 years. Now the public will be able to view them. I have a vacant corner lot in downtown Bertram , TX where they are being placed around 2 large oak trees. I guess I just wanted to share info so that one day I might be able to post pics. Thank you for your time and hope to participate in the future. If you are near Bertram I would love for you to come by and look. Project should be complete by mid March.

having been unable to go out a full day to search for fossils for several months due to health problems, thanks to a recent improvement I went yesterday about 100 km from my home to see a site where rudists were found. The first fossil encountered was a huge colony of cone-shaped bryozoans which had fallen and overturned in a depression. (can be 150kg?). I forgot to take my centimeter scale, so in the photos there is my foot, my hand or my fingers .... Then, I found a rock rich in small Exogyra and rare Rhynchonella. Finally, the rudists were there, in a wall (only for the photo, impossible to extract without damage, hope they will remain visible for the next visitors) and some specimen more fragile or altered in scree. I will post photos of the collected samples later because they are very muddy and require a good bath ...(Sorry, Franz, you have to wait some days ) For me it was a great day in the sun, just before the rain returned today!

Hi!! Two mystery fossils on a wall in San Sebastian (Basque Country, Spain). Other fossils in the same rock are Neridea. In the first photo, I wonder about the little "cells" that can be seen. Is this coral or something?? Looks different from other corals I've seen, and the shape is so strange! The second photo is a large shell? A rudist? A gastropod? Thanks for your help!!! :-) Elizabeth

I found this steinkern in the Maastrichtian, Peedee Form. of SE North Carolina. It is 5 inches long, 2 1/2 inches wide. Any ideas ? Thanks

Couldn't resist the pun..sorry y'all!! So went out to a friends ranch to do some fossil hunting. Wasn't expecting much because it said the area was Segovia and Edwards Limestone, which is not very fossilierous. You will find the occasional thing, but not very often. My friend showed me a few things she found and I was ASTOUNDED. A GORGEOUS Neithia bivalve completely encrusted in crystals in a chert/flint matrix. Very unusual. So that got me to really hunting. I never found a nice shell like hers but I did stumble upon a Rudist Reef! Also covered in crystals! All I had to do was look for the sparkles and there was another rudist! I love rudists (crazy looking Cretaceous bivalves, for those who are not familiar - the joke is if you find something you can't identify, it's probably a rudist), so this rock just has me over the moon. It's big, about 16 iches by 12 inches (you'll see my foot for scale...women's size 9 hahhahah) Some detail shots of the various Rudists: Plus a couple of other nce examples: Oh yeah...Foot for Size: The Lovely Bivalve Which I DIdn't Get To Bring Home: Also got to take some photos of the "local" fauna and flora - Axis deer is not really local, they are imported. but very pretty: A bit blurry picture of a Tanenger Purple Lantana: Bloooming Prickly Pear Cactus::

Fossils Reveal How Much Shorter Days Were 70 Million Years Ago
Oxytropidoceras posted a topic in Fossil News

Found this in Comanche Peak limestone formation in Central Texas. I'm thinking Eoradiolites quadratus but not sure if there's enough info to nail down species. Apex to apex measures approximately 1.5 cm for three different samples. I will slowly post more pics of the other specimens, as I reduce photo sizes without losing quality. Thanks for your help.

A few weeks after my mother found her most recent cidarid in an Edwards formation check dam, I took a few minutes to swing by the same dam to see for myself what else could be found. Within minutes I dug up a cylindrical fossil that for a few weeks puzzled me due to its resemblance to a belemnite phragmocone. Then on Wednesday night I went to the DPS meeting and afterwards met briefly with Professor Andy Gale and showed him this specimen. He identified it as a rudist and immediately corroborated that with another DPS member familiar with rudists. What confused me is that it doesn't look like any of the other rudists that I have found in the Edwards. So far in my research I have found there to be 4 predominant rudist genera in the Edwards, which are listed in the tags. From pictures online I can't seem to definitively match this fragment to any of them, but it at least resembles some caprinid rudists I have seen online that are not from the Edwards. I know there must be many more rudist genera in the Edwards that I am unaware of, so I am hoping anyone more familiar with rudists than me could at least narrow it down to more than just a likely caprinid. The specimen is 3.75 cm long (Fig. 1), 4.2 cm in diameter at its concave end (Fig. 20), and 4.1 cm in diameter at its flat end (Fig. 22). I really know next to nothing about them so any help is appreciated. If anyone wants to compare this with the many other rudists that I have found from these Edwards dams, see the excessive amount of pictures in this thread. Fig. 1. Fig. 2.

Hi, a friend of mine told me he found some Placentyceras in a place where the geologic ages go from the Albian to the Turonian-Santonian, but most of the stratas of that place are Cenomanian. I believe this fossil is not an ammonite, but rather an Oyster or a rudist. I mostly think about Requienia or Toucasia. The geologic file mention the name of Toncasia bayleia. Do you know if Toncasia is a synonym of Toucasia and do you think i'm right thinking this is a rudist ? Lenght : 7 centimeters.

Hello! Found a few things I cannot identify and would appreciate some help! I have done as extensive a search as I can and I am pretty sure the first specimen is a rudist. I think! Anyone care to confirm? The striations on the bottom "curve" intrigue me. The second piece is....I don't know what. Rudist again? The next piece might be an oyster? All were found in Hays County TX- Cretaceous, not sure of Formation. Thank you for your help! Also including in the next post my fabulous find of a tiny hippo head. Pretty sure it is an amazingly preserved head of a tiny hippo. HAAHHAH!!! Actually, and please let me know if ya'll concur, I think it is a very very worn echinoid. You can see a little bit of the shell (is that called test?) on it.
