This is a newly purchased ammonite, but I don't have any information, so I'm asking a question. The seller said it came from the Paja Formation.

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 thanks

Hi paleoguys! Some years ago a friend of mine found on the Isle of Wight-the UK (dinosaur coast/Barremian age) what seems to be a reptile bone. It looks like a transverse process or something like that. We have no idea. We'd be very grateful if you enlight us and solve this mystery. More picture to come...

A new Spinosaurid has been described from Spain's, Arcillas de Morella Formation (upper Barremian) , Vallibonavenatrix cani. Since this Spinosaurid has affinities to those in North Africa and may assist us in identifying material from Morocco. Paywalled https://www.sciencedirect.com/science/article/pii/S0195667119301302

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
