Since we all know that birds are dinosaurs how was your experience had a avian dinosaur as pet?

🦖 🦕

Imagine how much more fucking awesome life would be if society made dinosaurs less dangerous and implemented them into everyday life like if we learned to tame triceratops and could have them as pets as well as other less viscous dinosaurs. Don't get me wrong some dinosaurs are likely unable to be friendly and would always remain viscous and defensive but seriously imagine just walking around and just seeing dinosaurs walking around or flying.. that would actually be so cool.. it baffles me to think that there was a time where that really was the case.. that there was just dinosaurs roaming the earth..

67 million years ago, the Sun rises in the area that will one day become the four corners of the United States, on the banks of a river the distant alligator relative brachycampsa suns itself in the morning heat, these roofers and their floodplains provide an oasis in the other wise dry planes that make up the Southwest

Their bask is interrupted by the arrival of an alamosaurus, at 100 ft long and 60 tons is the largest dinosaur known to have walked the American continent and one of the last dinosaurs known, it comes down to the river for its drink, meanwhile a pack of 10 foot dromaeosaurs called dineobellator begin digging into the old footprints of an alamosaurus heard, why? Because they can smell food.... You see the alamosaurus are so heavy that they actually make the ground beneath them into quick sand and many small animals like turtles mammals and even dinosaurs get trapped in this and the smell of their death attracts predators.

Stalking the alamosaurus is a familiar evil, T-Rex, giant tyrannosaurus remains have been found in the Alamo formation but definitive T-Rex remains have been found in identical aged rocks in Utah just 3° of latitude North and it was discovered that tyrannosaurus as a genus originated in New Mexico 72 million years ago, so even in the vast dry plains where the prey is different this iconic Hunter remains the dominant force of nature, and the T-Rex isn't alone he's joined by his mate, with their brood having recently left they're able to hunt together again and they've decided to stalk the alamosaurs for food.

Not far away on the plains a glyptodontapelta forages for ferns a relative of edmontonia, it shares it's environment with ojoceratops, a close relative of triceratops and isolated remains show the two were similar in size, an 8 m long herbivore that weighs as much as an elephant.

Flocks of ornithomimids also run the land being the preferred prey of dineobellator other animals like the 9 m lambeosaurs r a bit too big and dangerous, what's interesting is these Alamo lambeosaurs or the last known for North America and with the age of the formation likely died out when the meteor hit, it's likely the vest dry planes were undesirable for edmontosaurus but for the lambeosaurs provided a refuge

Back to the herd the tyrannosaurs managed to make a successful kill, and flying overhead a quetzalcoatlus a pterosaur with a 36 ft wingspan lands on the ground, although it could challenge a T-Rex alone it wouldn't challenge two

Original piece done by me. Tag Atar3xia. Very loosely inspired by the dinosaur game Path of Titans. Theri is definitely a huge fav of mine.

In my sons dinosaur toys, I really like it, its like a short carnivorous brontosaurus with the midsection of a stegosaurus without the plates. Is it a real kind of dinosaur? Or just a toy hybrid.

I found this 2014 PBS Nova documentary titled Bigger Than T. Rex:

https://www.youtube.com/watch?v=zTo92vGtCe8&t=893s

This documentary provides an in-depth into how excavations in Morocco in the early 2010s by Nizar Ibrahim, Paul Sereno, and colleagues yielded the first substantial material of Spinosaurus, allowing for new information to be gleaned regarding the paleobiology of Spinosaurus.

Was wondering if anyone has any thoughts/recommendations for the most complete dinosaur encyclopedia. Looking for something that has quick references and a large catalog of creatures.

I think the closet we got to that was Spinosaurus, but it was still bipedal along with its relatives. And obviously every other theropod is bipedal.

How come we never got a full on quadruped carnivorous dinosaur in prehistory that would chase after its prey on all fours?

Still to this day paleontologists believe that zhuchengtyrannus and tarbosaurus r T-Rexes closest relatives tyrannosaur family. All are over 10 m long, they have similarly proportioned massive skulls and teeth. But is this really so?

Because tarbo and zhucheng (at the time) or older than T-Rex at 70 and 73 million years old as opposed to T-Rex's 68 to 66 Mya, scientists assumed that some tyrannosaurs migrated from Asia into North America and gave rise to tyrannosaurus, BUT. In 2024 scientist described a new species of tyrannosaurus from New Mexico named tyrannosaurus mcraeensis it's the same size as T-Rex but lived in New Mexico 72 million years ago, this raises some problems about the Asian migration theory because New Mexico is at the bottom end of North America the only possible examples of Asian migration between 73 and 68 million years ago is the centrosaur sinoceratops from 73 Mya in China and saurolophus from Alberta 69-68 Mya, but we really don't have much evidence of any Asian tyrannosaur coming to North America between that time if so we would have probably found them in the horseshoe canyon formation or Prince Creek formation since they preserve fossils from that time but the only tyrannosaurs from those formations are albertosaurus and nanuqsaurus which are not considered overly similar to the mega tyrannosaurs, so this raises my question

Were tarbo and zhucheng truly tyrannosauruses closest relatives or are there similarities convergence on similar this is happened before in the fossil record, for the longest time scientists thought the dire wolf and the gray wolf were the closest relatives of each other due to how similar the features in the skeleton are (the same prerequisite for the relations between T-Rex and tarbo and zhucheng) but in 2021 DNA showed that the dire Wolf was pretty distant to the gray wolf having converged 6 million years ago, and yet the convergence with them was so strong they were mistaken as close cousins for over a hundred years. Is the same possible with Titan tyrannosaur trio?

I believe so, 72 million years ago the world was changing, titanosaurs had migrated to North America likely from South America into the southern part of North America, global sea levels was falling vast semi-ared plains formed in the south, different from the lush floodplains earlier in the late Cretaceous, we know that campanian tyrannosaurs in the south were a bit different to the ones in the North, these are the teratophonines, which we're Southern North America's dominant tyrannosaurs during the campanian, what's interesting is that the type genus of the subfamily is known for having an exceptionally deep and robust skull, which is a very clear convergence with T-Rex, my theory is that this subfamily of tyrannosaurs developed into the first species of tyrannosaurus in the beginning of the Maastrichtian for two reasons A: the climate was drying and growing bigger allows you to go longer without food or water and B: the influx of new titanosaur prey which were big and dangerous probably required a bigger more powerful body to take them down.

Now why would tarbo and zhucheng develop such a similar body plan if not as closely related to T-Rex as thought previously? Both dinosaurs lived alongside a variety of larger somewhat danger prey, tarbosaurus went up against titanosaurs and hadrosaurs similar in size to itself if not bigger both prey items could trample it or bat them with their tails and zhucheng had coexisted with not just horned dinosaurs that were dangerous, but also shantungosaurus which at 50 ft and 15 tons is the largest hadrosaur of all time and would have been a massive challenge for any predator to kill. As a result all three had situations where they had big dangerous prey and likely needed similar body plans to take out such prey items. Therefore due to the similar lifestyles but big temporal and faunal differences, I believe these animals are not as closely related as is postulated but rather became so similar due to similar lifestyles.

And remember in North America the tyrannosaurs usually although in a dangerous environment on an individual level the prey were more equalized with predator most of the horned dinosaurs were around 20 ft while the tyrannosaurs playing on them were around 30 ft the horned the dinosaurs equalized this by being powerfully built and horned while the tyrannosaurs equalized it by having a powerful bite or hunting in packs, the hydrosaurus with the same size as the tyrannosaurs but the hydrosaurus were muscular and could defend themselves. They weren't as difficult to pray as titanosaurs or hadrosaurs bigger than yourself so they would not have necessitated the tank light proportions we see in the big three tyrannosaurs

I know this is kind of bold of me to believe but what happened with the dire wolf can shine light on how careful we need to be by making assumptions based off skeletal similarity

I hope my theory was interesting and meaningful if you agree or disagree let me know I'm open for debate that's what paleontology is for

Good day

The nemegt formation is probably end Cretaceous Asia's most famous formation being featured in docs from chased by dinosaurs to prehistoric planet, the most iconic creatures from this land is therizinosaurus deinocheirus tarbosaurus and more

Bagarataan it's a much lesser known animal, it's known at least to be a tyrannosauroid and is 3 m long. As exactly where it lies in the tyrannosaur family tree has been kind of up in the air. Elsewhere in China a new tyrannosaurid was found named Asia tyrannus, it was related to T-Rex and a true tyrannosaurid but it's only 4 m long and it was an adult showing not all these animals were the large apex predators

This leads me to my theory, bagarataan isn't just a tyrannosaurid but I believe it's an animal equivalent to Asia tyrannus, both lie within the same bigger family, they're both around the same size, and are both from formations that while different date to the Maastrichtian.

I believe there was a radiation and diversification of tyrannosaurs going on in Asia with them occupying various niches and resultingly developing such different sizes and body plans

The discovery of a tyrannosaur not only similar in size but also age to me at least grants my theory some credibility

Let me know what you think

Hi—I’m interested in finding a JP Institute book featuring some of my dino art. Anyone have some info? Thanks!!

T rex is the most famous,iconic dinosaurs in the world if not galaxy . When we think dinos we think t rex . You'd be hard pressed to meet somebody who dosent know it.

T rex is well studied by many palentologist Mr mark Scott Dr holtz Robert backer Alan grant ( I know he's fictional.but he's a palentologist so I count him. Robert Johnson palentologist and director Nigel Marvin ( he has talked about t rex at times and is a paleo zoologist ) Many more too

T rex has the biggest bite force ever .sorry honer but one bite and that spino would have been dead .

T rex had the thickest skull,jaws,teeth,skeleton ever .

It's very large

Documentaries ,movies ,books spread it's popularity.

" they talk about you like a freaking religion" Restraunts use t rex as logo,merchandise Theme park rides have t rex

This Baryonyx's arms seems pretty tiny

Didn't know Italy had weird dinosaur toys

I have a dino-obsessed toddler and for Christmas we're trying to find him more educational dinosaur books that are still engaging. We've run through just about every board book you can find (the How Do Dinosaurs series is a family favorite) and now we're hoping to step things up a bit. The kid has been saying 'pachycephalosaurus' before he was saying his own name, and at this point has learned around about 50 dinos if not more. Obviously we're trying to foster this love and keep the momentum going for him.

Hopefully this reaches the right people, like I said I'm just looking for suggestions for more educational but still engaging books. Age appropriateness isn't really an issue as long as there's no gore or anything of that nature. Thanks in advance!

I'll go first. Carnotaurus: Bull Lizard

Don't just deposit the mening of the name unless it makes sense as a name. For example: 'Tyrant Lizard' is a plausible name for an animal, but 'Gore King' isn't.

I'm going to Switzerland for vacation and I'm just wondering if there's any museums people recommend visiting. Ones with specimens that you can't really see on display in many places America.

Also, side tangent why isn't information easily excessable on the internet somewhere? Like why can't you search up "what specimens are on display in Switzerland?" Or "What museums have a Hatzegopteryx on display?" and just get that information? Like that doesn't seem like it would be that hard to make that information available, at least for the bigger more well funded museums.

Anyways, any recommendations you guys have would be greatly appreciated.

I posted this somewhere else, but nobody has responded yet. For anyone who doesn’t know, it’s an animated dinosaur movie on YouTube. It only has about 700 views, but I thought it was pretty great. Definitely not perfect since it was made by a 14-year-old, but he’s been pretty open to all the criticisms, and the sequel looks promising!

It can be anything like T.rex vs Triceratops and Velociraptor vs Protoceratops e.t.c.

I’m wanting to ask for a Spinosaurus tooth for Christmas, and I’m trying to find a reputable source. Is this one of them?
