Connecticut Dinosaur Print Specimen?
Maniraptora posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all! I’m considering buying this specimen which is identified by the seller as dinosaur prints from Connecticut, but first I wanted to make sure it’s what it claims to be, and not an instance of pareidolia or similar. I also was curious whether anyone here could offer some additional info on the prints—any guesses on age, formation, more specific locality, ichnogenus, etc.? Thanks in advance. I’m very excited to buy this if none of you have any bad news to offer! -

Hello everyone, I am a Belgian student in biology, and I love paleontology. Last week, I was walking on a slag heap near my home in the town of Marcinelle, at the coal mine called "Bois du Cazier". My attention was mainly focused on fossils of carboniferous plants (sigilaria, cordaites, calamites, etc ...). But at one point, I picked up this pretty little pebble which seemed to me to be a fossilized archosaurian egg. The slag heaps do not really respect the order of the geological layers, so it is very difficult for me to pin a year on it.

Today, instead of bemoaning the paucity of marine cretaceous rocks in my state, I reframed the situation as follows: "In the Cretaceous, most of Missouri was not ocean but land, with lots of exposed limestone that dinosaurs were likely walking around on." This led me to the following question: Do we have no fossil examples of dinosaurs that fell in sinkholes / caves / paleokarst and were preserved there, perhaps discovered during quarrying of the limestone? We definitely have such examples for fossil mammals, reptiles, etc., including Pleistocene (Ocala), Pliocene (Pipe Creek Jr.), a

So after following nizaar ibrahim's study in 2014 I learned that spinosaurus walked on four legs and it spend a lot of time in water being a good swimmer. But recently I saw that some new studies have been published and then some others and I have lost track so if someone could please inform me about the latest discoveries and tell me if spinosaurus was a good swimmer and if he walked on four it would be much appreciated.

Feather in cretaceous burmite amber? Cenomanian, Kachin State clay pits.
Amber Fluid Neutral posted a topic in Fossil ID
On the surface this looks like a feather but i don't know if there are any plants that look like this. Here are the pics. Piece extracted from the cenomanian clay pits. Dated by argon from volcanic crystals on strata to cenomanian age late cretaceous. -
Do you think this is a bird or reptile?

Someone told me that today is national dinosaur day today. If so, happy dinosaur day! @Troodon, @jpc, @Bobby Rico, and others.

How are fossils Given ID names? All dinosaurs have a group, be it Ornithoscelida or Saurischia, Genus/Species names, and Common names. They all have Their own Collectors and field notes, too. But the most perplexing part is how they have individual ID's. How did FMNH PR 2081 get it's name? or MOR 555? i know the first initials, FMNH and MOR stand for the museum they are held in, but what about the numbers 2081 and 555? what about the PR in FMNH PR 2081? I am asking so when i research dinosaurs, say U. Ostrommaysorum, I can find the actual fossils instead of museum casts, full (yet

The teeth are extremely small. Hard to see it clearly, but just wanted to know some general thoughts. I'm more worried about the authenticity factor. Also I'm assuming that this is a juvenille. Let me know what you guys think. Thanks.
