What is palæontology?

Literally, the word translates from Greek παλαιός + ον + λόγος [ old + being + science ] and is the science that unravels the æons-long story of life on the planet Earth, from the earliest monera to the endless forms we have now, including humans, and of the various long-dead offshoots that still inspire today. This community is open to anyone interested in paleontology, fossils, and evolution.

Ok so is there a possibility for Non Avian dinos to have Gular sacks? Like Todays Avian Dino the Frigate bird has a Gular sack, so is it possible for some non avian dinos to have it too?

What is your best book recommendation ?

I am just starting looking for informations about paleontology, dinosaurs especially. Im looking for books that show multiple specimens, explain maybe their behavior with some fun facts.

I read in english and in french if that’s important to know!

Some dino's name meanings are badass

A really cool example of this is "maip" that means: "shadow of death that kills with icy winds and wanders through the Andes" or pyroraptor that means: "Olympic fire thief"

Weird fossil

What if hypothetically you went back 60 milion years and you were among dinosaurs. If by some miracle you managed to survive at least a month, what do you think you could do/make/build to let humans in present day know you were there?

Where can I find a relatively comprehensive list of ordovician fossils? I found one that has completely stumped me.

Thanks y'all.

Why is the Megalodon’s dental band called a "bourlette"? I haven’t seen this word used elsewhere in English. It likely comes from French, but it is also quite obscure.

Are members under Avialae considered birds or not?

I've seen avialans get called birds while I only know everything under Aves (avians) as (true) birds. I really want to know if avialans can be considered birds, but I can't find a clear answer.
So, are all avialans considered birds or just close ancestors of Aves (proto-birds?), and are avians considered the true birds or just birds?

Just so you know, the only possibly Sauropody Specimen of Saurophaganax is the Holotype so we're good if we can change it to something else :)

From the experience of classifying birds, is it possible that some dinosaur classification is completely wrong?

Our classification of dinosaurs is basically all based on morphology. Birds are dinosaurs. The original classification of birds based on morphology underwent major changes in the 2010s, which severely impacted the "credibility" of morphology.

There were papers in 2014 and 2019 respectively that reclassified birds based on Whole-genome analyses, and the one in 2019 was directly certified by the IOC (International Ornithological Congress).

The most famous example, Falconiformes (Falcons), was originally considered to be under the Accipitrimorphae (including old world raptors and new world vultures), and is closely related to other raptors.

However, after genetic research, it was discovered that they are actually closely related to parrots and finches, and together they form the Eufalconimorphae.

Think about it, falcons are more closely related to sparrows and parrots than falcons are to eagles. This is a conclusion that is difficult to infer from morphology.

So, is it possible that our classification of dinosaurs is totally wrong? Just like the classification of birds (a category of dinosaurs) is so wrong?

Where there any small aquatic reptiles?

Nowadays we have sea turtles, sea snakes, and sometimes salt crocodiles and gal iquanas and back then you always hear about mosasaurus, kronosaurus, and icthyasaurus, but were there any smaller aquatic reptiles back then? Surly they can’t all be whale sized

New story added to Prehistoric Wild: Life in the Mesozoic (Hostile Crossing)

Proud to announce that my short story collection, Prehistoric Wild: Life in the Mesozoic, has been updated with its 33rd entry. Called "Hostile Crossing," it takes place in the Elhraz Formation of Early Cretaceous Niger, 112 million years ago. In it, a herd of Lurdusaurus, including a mother and daughter pair named Musa and Bala, make their way across the swamp waters only to encounter a group of voracious Sarcosuchus. This is among the oldest ideas I've had in mind for Prehistoric Wild, making it one that I was very eager to write up. Plus, what better time to have story with such a suspense-filled premise than this close to Halloween? Can't wait to hear what ya'll end up thinking of it. https://www.wattpad.com/1489035576-prehistoric-wild-life-in-the-mesozoic-hostile

Why did carcharodontosauria disappear randomly?

I was just wondering why they all seemed to disappear after 90 million years ago. Even though it seemed like they were at their prime. Was it clinate change? Competition with new predators?

Am I the only person skeptical that (flightless) theropods had those large flight feathers on their limbs? Wouldn't they interfere with normal life? (art by ABelov2014 from Wiki).

Carnivore dinosaur with no category?

I need help.

I don't remember the name of the species but I remember about a carnivorous dinosaur (looking kinda like Allosaurus) that had no "category" and by that I mean it was still debated if it belonged to Megaraptors, Abelisauroidae, Carcharodontosauridae etc.

Help with finding the species would be greatly appreciated.

Did other abelisaurids have eyebrow horns?

I was curious to know if Carnotaurus was the only abelisaurid with eyebrow horns when I was looking at the Path of Titans Pycnonemosaurus which has 2 variants with horns and 1 without horns. Was curious there was any evidence of that or if it was purely speculative.

What was the largest rodent with a tail?

A quick Google search tells me j.monesi was likely the largest rodent ever. But they are believed to have a more cavi type of build and lifestyle.

What was the biggest tailed or rat-like rodent? I’m partly asking because I find the “giant rat” enemy in fantasy games to be kind of boring. Looking for a real animal in the dog-size range.
