Hi everyone, This little guy comes from Carniol, France. It is from the "Gargasian", Aptian, Cretaceous. Surprisingly, unlike most other finds (so everything except for belemnites), this one doesn't seem pyritized... Anyways. It's pretty flat (because of geological processes flattening it; my gut feeling says that naturally it is meant to be much rounder). Now I'm really not sure if this is a weird heteromorph ammonite or a weird gastropod. I would guess that it is a gastropod simply because they are much more common, but it just looks so weird that I'm stumped. Hopefully you guys can solve my little mystery! If better pictures are needed, which will probably be the case, I will make them. Thanks in advance, Max

Hi all, Here are a gastropod and a bivalve that I found in Carniol, southeastern France this summer. They are from the "Gargasian", Aptian, Cretaceous. The pictures aren't fantastic, so if needed I can retake them. Thanks in advance, Max #1 A gastropod (surprisingly not a steinkern, but the shell itself!). Preservation is surprisingly good I find for something this old, especially taking into account the fact it's been replaced by pyrite!

Hi all, Here are some fossils I found at this summer in Carniol, and I would like to know what they are. If the species can be said that would be fantastic. So, the fossils are all from Carniol, France. They are from the "Gargasian", of the Aptian stage of the Cretaceous, some 120'000 years old. Looks like they're all pyrite-replaced. I believe they're some kind of cephalopods, but I'm really not sure. What are your thoughts? Thanks in advance! Max

Hello! Here is the small preparation sequence of the Lower Cretaceous (Aptian) ammonites Nodosohoplites subplanatus Egoian, 1965 from the North Caucasus of Russia (Krasnodar region, bank of the river Hokodz).

Hi! I dunno if someone can help me. This coral was found a year ago with several other still with no ID aswell. The outcrops are aptian in age. Can you give him a name?

This is the first in a series of some of the pyritized ammonite fauna from the Provence in southern France which I'll be posting bit by bit over the next week or so. During a summer vacation a few years ago I spent 3 weeks walking, or sometimes climbing up and down the marly hillsides with my nose to the ground, checking out ravines and gullies on my hands and knees in search of these miniature jewels which regularly weather out of the clayey Early Cretaceous sediments. There are similar sites in the Jurassic, but they were too far away from our cottage. I visited exclusively sites in the Valanginian which, according to Kilian(1907-13), houses over 90 species, and in the Aptian, the age named after the locality Apt in the Provence. Practically all of these ammonites are mostly the inner whorls of the phragmocone, or at the most complete phragmocones of what in many cases were much larger creatures.
