Hi guys found this over the summer from the aptian of the Isle of Wight vectis fm shepards chine member. It looked like the top of a lungfish tooth what do you think? I might just be seeing things.

Found these two partial teeth in my fine material from Carniol France. Aptian - Gargasian One is just the blade the other is just half the tooth. My best guesses are for the half tooth Cretolamna indet. and Protolamna indet. for the blade. Does this make sense or should I keep them as indeterminate shark teeth? scale is mm

Still more sorting to do but the belemnites are done. I am struggling to understand the differences between the different Neohiboletes. looking at http://le-coin-a-fossiles.fr/Gargasien.html there are three known species also from the topic below there are diplobelenid phragmacones

As a later summer vacation we decided to do a road trip - Tour de France. France having many interesting destinations and things to do and collecting fossils would be one of them. As we usually don’t plan our trips beyond a few days ahead also the fossil locations were decided on the road. But when reading about Carniol it became clear it was one we had to include. Other non fossil highlights of the trip were Bordeaux, the Pyrenees, Toulouse (great museum of natural history), Lyon and of course Pont du Gard. When finding out about Carniol I did some further reading on how to get th

This jaw fragment was found when washing clay that I brought from Carniol. Cretaceous, Aptian, Gargasian. On Reddit it was identified as Saurian and I was hoping (but doubting) a more accurate identification would be possible. Really happy with this find anyhow. more information about Carniol and my trip there

This tooth was a surface find from Carniol. It was found by my partner and she just put it in her box without telling me recognising for what it was. Nice surprise when sorting / cleaning. On another forum a similar tooth from the same location was identified as Protosphyraena. Cretaseous, Aptian, Gargasian. There are no serrations visible under 10x magnification. At the base the toot is about 5.8mm wide and 4.1mm thick.

Hello I found this piece of sandstone along the Athabasca river just south of Fort McMurray, Alberta, Canada. Since it’s sandstone I’m assuming it came from either the Mcmurray (late barremian or early Aptian) or Grandrapids (Albian) formation although my geology skills are not great. I tried to do some googling on what it could be but I found no results since I couldn’t be specific enough since I don’t really know what I’m doing. Any ideas? I attached an image of the location for fun that I took a while before I found the rock. I found it to the right of the creek tha

North Texas Central Cook County Antlers Sand Formation
Creek - Don posted a topic in Fossil Hunting Trips
Nice weather here in Texas today. Took a advantage of the warm weather (70's) and went out fossil hunting near the Texas - Oklahoma border nearby Red River. Area is a mixed Antlers and Goodland formation which sort of overlaps each other. Sometimes you will see Antlers Sand formation above the Goodland formation, etc.,. I came across what appears to be a impressive Antlers Sand formation sandstone cliff. These deposits seems to be a fluvial deposits from early Cretaceous period. I could see the river pebble stones embedded in the cliffs. Measured cliff height of about 120 feet. I- 7 replies

Hello there! A year ago I bought a fossil fish from Brazil at a convention, yet I am unaware of the animals genus. The fossil has a lenght of 37 cm's, and a skull the lenght of 7 cm. 0,7 cm is the average lenght of the individual vertebrae, 39 vertebrae are vsible in the fossil. Skull bones: Maxilla: 4 cm Subopegulum: 4.6 cm (lenght) 3 cm (height) Operculum: 4.6 cm (lenght) 3.5 cm (height) Dentary: 3,2 cm Height of Tail Fin: 7.9 cm Age Location: Presumably Romualdo Formation, based on Matrix and Preservation Aptian-A

Hi, several months ago i found a very tiny and rather flat urchin in a block which had two spines. I managed to disengage the urchin, but it is really too tiny for my camera. The spines are bigger and i wondered to what family of urchin they belong (maybe a cidarid ?) I also join the photos of the urchin that was with them (although i don't know if that would help). @Coco @caterpillar ? The smallest spine : The bigger :

Tiny Texas dinosaur finally has a name nearly 35 years after discovery. The new ornithopod is called Convolosaurus marri. Material from a minimum of twenty-nine individuals of a new ornithopod, represented by nearly every skeletal element, was recovered from the Proctor Lake locality in the Twin Mountains Formation (Aptian) of north-central Texas News article https://www.dallasnews.com/news/science-medicine/2019/04/04/tiny-texas-dinosaur-finally-gets-name Paper https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207935 A new basal orn

Hi everyone, Should've posted these a LOOONG time ago, but me being the lazy guy I am I forgot to do so till now Anyways, here goes. These were all found by me (/my family) in the Carniol clay banks in southeastern France. They are (heavily for some) pyritized. They are from the "Gargasian", Aptian stage, Cretaceous. Would love to hear the species name of them. Genus is still fantastic. Thoughts? Thanks in advance, Max #1:

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

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
