This fossil was found last week by a worker of the quarry. I haven’t seen this kind of fossil before and is definitely an uncommon one around here. The fossil is not in a really good condition. I’ll post two pictures hoping I can find some help from you guys. The largest teeth are almost 1 inch long. Thanks a lot!

Hello, I recently acquired some fossils from the Vallecillo member of the Agua Nueva formation. The Agua Nueva Lagerstätten is famous for its perfectly preserved fish and marine reptiles. It is late cenomanian in age about 90-93 million years old. I got two large ammonites from one of my trips to Mexico. I was wondering if someone can identify it to the family, and possibly the genus level. They are preserved in a finely bedded shale. This one one is the largest one it is about 8 inches long.

Hi there! This is my first post at Fossil Forum, hope this information could help in getting some help to identify this fossil. It was found at a quarry in Vallecillo, Mexico (northeast part, less than 100 kms from Laredo, Texas). The fossils found here belong to the the Vallecillo member from the Agua Nueva formation, aparently from late Cenomanian to early Turonian. The full length including the separate vertebrae is aproximately 29 inches or 74 centimeters. The longest tooth is aproximately 1.4 centimeters long. I was only able to post a single picture, hope it helps.

Has anyone seen Meg teeth from Mexico? I'm currently working in Mexico and one of my coworkers is trying to sell me a big Meg tooth that looks very similar to the North Carolina teeth.

Hi, I found this giant oyster in the Mexican Golf. It weights around 13kgs. I found this article about something similar, where they did a MRI on the oyster. - https://www.dailymail.co.uk/sciencetech/article-2154813/amp/The-100-million-year-old-oyster-times-normal-size-undergo-MRI-scan-contains-worlds-biggest-pearl.html and here the same story with more details, but in spanish - https://insolitonoticias.com/ostra-fosil-de-145-millones-de-anos-podria-contener-una-perla-gigante/ Cheers.

Friends, I seek help to classify them, I have acquired them over the years without any reference. What I have been able to investigate is that they are from the Kimmeridgiano-Portlandian, probably from the formation "cañon of las lajas" (San Luis Potosí, Mexico) .I look for your name and surname.

Friends, this time I seek the help of a connoisseur of fossil corals, they are from the Neocomiano (Lower Cretaceous), from a town near Tehuacán, in the State of Puebla (Mexico). The scale is in centimeters. I appreciate your help because although I have dedicated myself to reading the scientific literature of the area, I am an amateur, and many of them are very similar. Of those who have an idea, I put their name for them to say. regards

Ochetoceras zio is one of the many species in the genus Ochetoceras. However, this particular species Ochetoceras zio is based only on one specimen, that was found in Württemberg, Germany. If the ID is correct, this specimen would be the 2nd one of its species ever found!! It comes from the Taman formation, probably the lower member, which is mid to upper kimmeridgian in age. It was found in association with Aulacomyella sp., which is abundant in the lower Taman formation and almost absent in the upper Taman formation. Special thanks to, @Ludwigia for identifying the specimen here on the Fossil Forum.

All of may not know this, but the Middle Jurassic La Boca Formation in Mexico boasts the most important Middle Jurassic tetrapod fauna in North America outside the US. Among the notable fossils found in the La Boca Formation are primitive mammals, sphenodonts, and even archosaurs (incl. the pterosaur "Dimorphodon" weintraubi and an unnamed mesoeucrocodylian). When compared to other Middle Jurassic faunas, it's interesting that the tritylodont Bocatherium is roughly the same age as the other two Middle Jurassic tritylodonts Bienotheroides and Stereognathus. As some of the components of the La Boca Formation vertebrate assemblage are related to their counterparts in China and Europe (e.g Bocatherium), future discoveries in the La Boca Formation could provide a new window into the biogeographic origin of the Morrison fauna, and it's not implausible that the Morrison fauna may have originated in Patagonia.
