For exemple the biggest bird flying bird to ever exist Argentavis had a wingspan of 7 to 7.4 m/23 to 24,3 ft, while the biggest pterosaurs Quetzalcoatlus had a wingspan of 37 to 40 m/11 to 12 m, why this happen?

I need to find that bir

I’ve recently found myself interested in dinosaurs, and I was wondering what would be a good way to learn more. Any good documentaries, books, websites? Thanks in advance.

When I see dinosaur pictures I'm like, shouldn't they be chubbier? When I see the Jurassic park picture of a t-rex I look at it and I just think they put skin over the bone and called it a day because we don't actually know 100% what a dinosaur looked like, but when you look at an elephant skull you can see it looks nothing like an elephant, elephants are chubbier and have more fat. Couldn't we apply this knowledge we have of elephants and other animals into dinosaurs? Or did they already do this and I'm just ignorant? (Sorry, my dinosaur hyperfixiation was 11 years ago when I was 3)

I have been wondering, if pokemon were to be about dinosaurs what would the three starters be? My current thoughts were Grass: Corythosaurus Fire: Concavenator Water: Baryonix

My personal favorite is the Spinosaurus because of Jurassic Park 3.

Hi, like the title says. I haven’t ever heard of how the world reacted to the first findings and then the next findings etc. Of course many religious institutions probably had a negative or dismissive reaction. How else did it affect the globe? A documentary is mainly what I’m looking for. Thanks!

I´d really like to have a poster of any sort of extinct animal or paleontology related thing but I can´t find any good ones on the internet.

I'm trying to figure out what dinosaurs this toy would resemble the most. If any dinosaur nerds have any ideas, lemme know. I want to draw a redesign, and I'm trying to find a good starting point. Part of me thinks something like a Charcharadontosaur due to the long arms and long snout. Another part of me thinks something more akin to a Megaraptor as a more agile creature due to the leopard/Jaguar pattern and the hand shape showing it would have more fingers. If you wanna see more images, look up (Plush Leopard Spotted Spots Large Dragon B J Toys Stuffed Animal Toy 14")

whether it is a species or a specimen

If we take into account its bite force, Trex basically spent little to no effort in surviving. It could simply turn anything into goulash just by biting it a single time. A 30 meter tall sauropod? It could bite its leg and paralyze it by the sheer physical pain. A Giganotosaurus? Turned into ashes in SECONDS. As many people have already proven, other large theropods comparable to Trex in size would get reduced into dust by this absolute cancer to the ecosystem. This animal had no rivals, everything was just a snack for it. Without the asteroid, it would have eventually sent to extinction any large theropod or sauropod in north america.

Hey everyone, I'm a first time writer, and I'm creating a paleo-horror comic involving dinosaurs from the cretaceous era. I'm right now in the first draft stage of writing the story.

I want to make the dinosaurs as accurate to life as possible, but I'm struggling to find reliable and up-to-date sources. I'm especially concerned about writing specific dinosaurs because there could be a lack of information on them, such as the Therizinosaurus, Shantungosaurus, Quetzalcoatlus, Diabloceratops, Achillobator, Utahraptor, and etc.

Suggestions on good and reliable sources on the latest dinosaur science would be very helpful!
