Hi everybody. Hi everybody, i've found those garsteropods in the cenomanian of Charentes-Maritimes, South-West of France. I thought the first one can be a worn Neoptyxis fleuriausa, but i'm not sure. The last looks like a Conus. I thank you in advance for your time and answers. Sophie. 1) 2)

Among my founds i have Rynchostreonae, Pycnodonts, and also Rudists : a Polyconites, some Sphaerulites and some pieces of Ichthyosarcolites. But i wonder about this piece. Is it a Rudist, an Oyster, or something else ?

Hi everybody. I ask your help once again to help me find what kind of shells are those two tiny and cute things : First, there is that column beside a brachiopod. It is between seven and eight millimeters of long and three millimeters wide :

Hi again, here is the last piece i found from the cenomanian that could be sponge. It is calcitized because it fizzes with vinegar, so i think it also could be a strange concretion. If it's a sponge, in the book on the fossils of Charentes-Maritimes i have, the closest looking-like sponge photo i found is a Doryderma sp..

A new fossil hunting in the Charentes Maritimes
fifbrindacier posted a topic in Fossil Hunting Trips
Hi, last week i was in holidays in the department of Charentes Maritimes, in a place where you have kilometers of uncovered seabed and where the nearest isle is reachable by foot when the tide is low.

Hello again, always in the cenomanian of Charentes-Maritimes in France, i have those pieces. I think they are sponges. 1) 2)

Here is another piece which, i believe could be a sponge. It looks like a stachyspongia, but i see that it's a Campanian sponge.

I present you this tiny thing that sticks on an oyster shell. I believe it has great chances to be a sponge, what do you think ?

From the album: North Africa
Given to me as a gift, this is Rhynchodercetis from the Kem Kem beds of Morocco; possibly R. yovanovitchi, although I cannot make a definitive identification. The specimen is complete, although the state of preservation is not superb; the skull, vertebra,ribs, and rays in the fins are all visible, but not in fine detail. -
A couple of years ago, while on a romp through the Rio Puerco Valley, I found this ammonite. Since then, I have attempted to find a proper i.d. for this specimen through literature and documentation of New Mexico's Late Cretaceous ammonites. With very little luck, the closest resemblance were ammonites in the subfamily Puzosiinae, which are not documented from New Mexico. Today I decided to show the curator and the ammonite researcher at the New Mexico Museum of Natural History and Science. Good news...they did not know what it was! ...pretty exciting. Anyhoo, I have donated it to be studied but figured I would post it here as well. Unknown ammonite from the Late Cretaceous (Cenomanian) Paguate Mbr. of the Dakota Formation - New Mexico, USA. I doubt they'll be jumping on this right after lunch, but I will let ya'll know the results as I do. Happy hunting, -P.

A trip to Haute Normandie (France) cretaceous cliffs ( The plasterers' balad )
elcoincoin posted a topic in Fossil Hunting Trips
A trip to Haute Normandie cretaceous cliffs ( The plasterers' balad ) - Part 1 During three days we travelled along the Haute Normandie coast. The area we ventured in is cretaceous : cenomanian (-99 MA), turonian (-93 MA) and coniacian (-89 MA), following the west to east dip. Day 1 : Antifer We met in Saint-Jouin de Bruneval, on the beach parking lot next to the oil terminal. We started the trip at 9 am, so we could hike quite far before the tide would stop us. Sky was shiny and quite fast the temperature started to rise. We mostly spent the morning looking for fossils in cenomanian boulders and chalcedonies among the peebles. We let the tide lock us and made a break for a picnic and a nap. Once the tide let us, we started again to look for fossils, under a scorching heat. At about 6 pm we made our way back to the cars. The beach which was empty in the morning was now overcrowded. We mostly found some irregular echinoids : crassiholaster and catopygus (some with a really nice preservation), some brachiopods, some bivalves (most fragile) (including nice rastellum) and 2 shark teeth. Here's a geoligical presentation of the area (in french unfortunately) http://craies.crihan.fr/?page_id=13478 Some of my finds on that day : heres a link a my flickr galery for the whole trip : https://www.flickr.com/photos/48637020@N06/albums/72157682540354264 Crassiholaster subglobosus Crassiholaster subglobosus Crassiholaster subglobosus with a smal bivalve print Catopygus colombarius more to come soon...- 11 replies

Recognition trip to the Ifezouane Formation, South of Morocco
Juan A. Poblador posted a topic in Fossil Hunting Trips
Hello everyone! Details of an outcrop of the Ifezouane Fm (Upper Cretaceous- Lower Cenomanian) in southern Morocco. This outcrop is very close to the border with Algeria. Sandstones and gravels have very well defined sedimentary structures, mainly cross stratification. Are a clear indicator of the current regime that possessed those ancient and enormous systems of braided rivers. In one of the photos you can also see one of the artificial tunnels excavated by local miners in search of large vertebrates, quite abundant! However, this type of sediment, deposited in a relatively high energy ...., accumulated the remains of many animals dragged by the current, also eroded and disarticulated. That is why it is very common to find isolated teeth and bones. But rarely articulated. The red color of a sediment that is seen in one of the photos is not Cretaceous! It is a recent breach deposited above the Cretaceous that lies at the foot of the slope. Greetings Juan

Hello everyone! Today I'm fighting with this special piece !. I have been doing a lot of comparisons with other similar remains, but unfortunately there is very little published. It comes from the Cenomanian stage, of the Cretaceous region of KemKem (South of Morocco). Concretely of the red sandstones of the Aoufous Formation. Of the basal levels, really difficult to differentiate from the Ifezouane Formation (with much more sandy nature than the clays of the Aoufous Formation). I forgot the scale at pictures! Sorry! It measures long: 32mm = 1.25 Inch It looks a lot like pterosaur cervical vertebrae. It has some very special characteristics! I would like anyone who wishes to contribute with their opinion. Help is always welcome!

Couple of two scapulae bones. Cretaceous Cenomanian Ifezouane Fm
Juan A. Poblador posted a topic in Fossil ID
Hi all! Here I share with you a couple of jewels that I discovered a few months ago working on the yellow sandstones of the basal levels of the Ifezouane Formation (Upper Cretaceous Cenomanian of South of Morocco). The truth is that it was a huge surprise !. These are two scapulae, right and left of the same individual. But individual of what? I was astonished to recognize the absolute rarity of its characteristics. It has a very developed proximal epiphysis and with great articulation surface. Distal area is beautifully ornate! The autapomorphies are really rare !. It had been a long time since I had encountered something similar! Now I have begun to look for bibliography on similar remains to begin the first comparisons, but it is being complicated task .... I also enclosed a photo of the level at which I dug it !, fine-grained sandstones lenticularly interleaved (like patches) within gray marls. Any opinions? Thanks!
