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 mean the rare ones, I mean there's absolutely NO WAY to legally purchase them. I've seen the usual suspects on almost every website. Tyrannosaurus, Spinosaurus, Triceratops, Ankylosaurus. As well as certain Raptors, Pterosaurs, and theropods here and there. There are certain popular dinosaurs I never seem to come across though. Giganotosaurus? Brachiosaurus? Suchomimus? Are these dinosaur fossils just hard to come by or are they unobtainable to the average collector? If they are available, what's the best way to obtain them?

HI! I am Ashton, I love fossil and paleontology! I also love anything to do with science, animals, and nature! My favorite dinosaurs are all the weirdest ones like Deinocheirus, Concavenator, and Spinosaurus.

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.html Holotype metatarsal II http://cdn.sci-news.com/images/enlarge8/image_9426_2e-Tamarro-insperatus.jpg Artist's reconstruction (Oscar Sanisidro): http://cdn.sci-news.com/images/2021/03/image_9426_1-Tamarro-insperatus.jpg

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.

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.

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.

Hey everybody! Im JT, 31, hailing from the Seattle area in WA. I started collecting fossils, mainly of dinosaurs, last year. I've viewed some parts of this forum for a while, but finally got around to making an account. Big thanks to everyone here for contributing and sharing their knowledge, the wealth of information on this site is fantastic. Hoping to go on a dig in the midwest in the next few years, a bucket list dream for sure. Cheers

Hello my name is Alex and I just found this site. I have always been interested in fossils of marine reptiles as well as dinosaurs and hope to build a small collection of both. thank you

I am making a book showing evreyone that dinosauria is part of squamata. You will realize all of you are wrong when it comes to dinosaurs (thats how good it will be), I want to challenge pre concived notions and fill them with new ones. If you want to have a conversation with me that would be great!

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 picture of my son Alex and wife Izzy + AJ. Now on with the other pics.

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.

Should I restore this, or Keep as is? T-Rex gastralia.

Hi everyone, do you all think this would look better with the cracks filled and fully restored or as is?

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 thread for updates with future finds. I’m very proud to say that much of my collection, mostly the dinosaur stuff, has been found by me rather than been bought, though there is a lot of money invested here. If you would like more or better pictures, info or would like to help me ID anything in this collection that I’m unsure about (I’m severely lacking in physical labels at the moment) don’t hesitate to ask.
