  2. Unknown Fish Genus

    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-Albian More Pictures in the comments, I am, somehow to dumb to know how to make an image smaller

  4. Urchin spine

    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 :
  5. New Texas Ornithopod Named

    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 ornithopod (Dinosauria: Ornithischia) from the E Cretaceous of Texas Kate A.

  6. 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
  7. Shells from Carniol

    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!
  8. Ammonoids from Carniol

    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:
  9. Oddballs from Carniol

    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

  22. Dufrenoyia furcata (Sowerby 1836)

    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.
