Hi everyone, found this in a new jersey cretaceous creek. Looks like a partial enamel something but I'm not exactly sure what it can possibly be from, it interestingly has some very defined ridges on the least worn side. Very hard to catch the clearest pics to show the sharpest definition but I tried to get the best I could. Maybe this can be a clue to a potential id. Pictures of it with whiteish background are upside down.

This may sound like a stupid question to the more seasoned collectors, but I've recently started buying dinosaur teeth to collect and I can't help but notice a pattern when searching through the various fossil websites. Almost all dinosaur fossils are American or Moroccan. I've seen that international fossil trade is actually illegal in some countries causing some fossils to be unobtainable realistically. Some fossils are also extremely rare as well and are valued much higher making them extremely difficult to find.. Is it really that common for dinosaur fossils to be unobtainable? I don't mea

A new genus of Troodontid has been described from late Maastrichtian fluvial deposits of Spain's Talarn formation (Tremp Group). It was named Tammaro insperatus named for a small, elusive creature from local folklore and the latin word for unexpected due to where it was found. Very interesting to see this family of dinosaurs officially represented in Europe's fossil record, along with the overall diversity on the continent when it was still archipelagic. https://www.nature.com/articles/s41598-021-83745-5 http://www.sci-news.com/paleontology/tamarro-insperatus-09426.htm

The Advanced Dinosaur Egg Guide Please share this with those who have egg questions. When possible, technical terms were avoided or defined. Every effort has been made to ensure accuracy, but it is always important to do your own research. This guide is merely a snapshot of information taken from many scientific publications. I am not an expert on eggs, rather I just love sharing what little I have learned over the years, what science has learned over the years. For an overview on how to spot a fossilized dinosaur egg and the sizes of eggs, see the basic guide:

Breakup of a long-period comet as the origin of the dinosaur extinction
Oxytropidoceras posted a topic in Fossil News
Astronomers: A comet fragment, not an asteroid, killed off the dinosaurs Jupiter's gravity pushed comet toward Sun; comet was ripped apart by tidal forces. Jennifer Ouellette, ArsTechnica, February 15, 2021 https://arstechnica.com/science/2021/02/astronomers-a-comet-fragment-not-an-asteroid-killed-off-the-dinosaurs/ The open access paper is: Siraj, A. and Loeb, A., Breakup of a Long-Period Comet as the Origin of the Dinosaur Extinction.

I found this specimen along with some other fossils during a fossil hunt. This vertebra is very peculiar and unique, due to its small size, and it’s composition. It is completely permineralized by hematite, making it feel much heavier than the average rock. It almost feels like a chunk of metal. Probably belongs to one of the endemic hadrosaur species of the Cerro del Pueblo Formation, such as Velafrons coahuilensis, or Latirhinus uitstlani.

Well, I figured that I should start a member’s collection. Sorry for my absence, I was busy with college classes. I did great this semester, and I even won a student leadership award! With that being said, I’m gonna start my collection off with a piece that I acquired for my birthday! My 22nd Birthday is tomorrow (June 14th), and I was strapped for money. My father and grandmother chipped in, and helped me acquire this chromium woodworthia piece from a local rock shop that I frequent! It’s from Arizona, and it only cost $60 USD! I’ll try to be active here whenever I can

Giganotosaurus Tooth? Or Carcharodontosaurus Dinosaur Tooth Fossil
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone, I was recently offered this Giganotosaurus tooth. I was wondering if there was a way to distinguish it from carcharodontosaurus teeth from the kem kem beds? Or if anyone can share there opinion on this one, thank you. -

Did not know where exactly to put this post however as South America is the nearest country to Antarctica, it's here. I have been recently very interested in learning about dinosaurs from this area over most others and here's some info on the Antarctica. Imagine how it would be like to explore the coldest place on Earth and the challenges that one may face when trying to identify material from this location. A fully fleshed-out Cryolophosaurus is on display at the Natural History Museum LA. Photo by Charly Shelton. Antarctica was not always a frozen

Hi all I really think the Hadrosaurs were very cool dinosaurs and not just as a food source for the T.rex. So in celebration of the great beasts please show us your Hadrosaurs material . Hadrosaurs are dinosaurs that are members of the family Hadrosauridae, and include ornithopods such as Edmontosaurus and Parasaurolophus. They were common herbivores in the Upper Cretaceous Period of what are now Asia, Europe and North America. Edmontosaurus annectens Metacarpal V found at the famous Hell Creek Formation... Late Cretaceous Period Montana. The missing one in photo tha

What is your "wish list"? My wish list, i think is this: 1) Morrison fm Sauropod tooth 2) Acrocanthosaurus (I know that is very, very rare and i will never get one) 3) Troodon tooth 4) Suchomimus 5) Ceratosaur tooth 6) Morrison theropod 7) Dimetrodon tooth 8) Tyrannosaurid tooth 9) Acheroraptor 10) Pliosaur tooth I write only about dinosaurs, reptiles and synapsid because if i will add more clade, is very hard to make the list.

Dinosaurs and reptiles size estimation with teeth
PetrosTrilobite posted a topic in General Fossil Discussion
Is it easy to find the size of the animal with a tooth? For example, i have a spinosaurid tooth from morroco 2.75 inch long (approx. 2 cm is root), a large mosasaur tooth about 2 inch, a Carcharodontosaurus 1.94 inch. My estimation: my spino tooth belong to an animal about 7-10 meters long if it is a of the large teeth on this spino mouth, for the carcha i think that came from the middle or the back of the jaw of an animal 5-8 meters long, and the mosasaur from a 7-8 meters long mosasaur, and is a very thick tooth. -
Yesterday I received received a PM from Rich @stats to see if I wanted to go collecting with him on Mazon Creek, but I told him that I had to pass since I was going to the zoo with my grandson AJ. Now, if I was just going with my wife to the zoo, I would have been on the creek right now collecting- It was a great day, with great weather and there is no better way to spend a Sunday that with my son and his family. Here are a bunch of pictures of the exhibits, it was great for everyone. Here is a picture of me and AJ. And now a pictu

Chenanisaurus Barbaricus Tooth? Or Carch?
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Came across this tooth labeled as an abelisaurus belonging to chinanisaurus barbaricus from the Maastrichtian supposedly found in the phosphate mines of the Ouled Abdoun basin. Looks pretty thick to be abelisaurus and comparable to an extent to some carcharodontosaurus teeth. Is there a way tell the difference or will there need to be more specifics involved. -

Hello all, I was waiting a while to show my ever growing collection until I finally got this new shelf. I wanted to paint it to look similar to my other shelf, install these neat colour changing lights, organize things and move everything...then take photos! I had stored everything in my bedroom for a while but now everything is front & center for visitors. As has has been made obvious by my many ID posts and couple threads in the, “fossil hunting trips” section, I live in a fossil rich area have access to much land to collect from frequently, so I will use this t
