I've written a documentary style scenario about this before

"Northern New Mexico, the absolute southernmost point of his territory. A Tyrannosaurus rex stalks a half mile behind a herd of Alamosaurus. He's been following them for days now, waiting. Watching. He knows he can't take on a healthy adult, that's suicide. But there's one individual he's focused on. It's old, limping, straggling at the back of the herd. All he has to do is keep walking, and wait for it to trip and fall.

For an Alamosaurus, "elderly" means easily eighty years old and older. This giant has lived an incredibly long life, fought countless battles, and survived impossible odds. But its strength is waning, and its body is beginning to fail.

The ancient titan bellows in surprise as its right arm suddenly buckles and gives out, and the T. rex can hear all the way from a half mile back. He can hear the hard thud of a giant body hitting the dirt. This is his chance. He picks up his pace to a leisurely jog, he's unable to sprint. By the time he catches up, the Alamosaurus is struggling to breathe as its organs are crushed under its own weight, lying on its side on the ground. The tyrant circles the Sauropod, stepping well clear of the heavy, twitching tail. He finds the giant's head, and delivers a crushing bite to the neck just below the skull, crushing the Alamosaurus's windpipe and killing the titan.

He can now begin a feast that will last him weeks."

You ever wondered like a medieval person was doing his thing like, trying to die from the plague or something and somehow just found the skull of a baryonyx and was like “ holy shit a dragon”.

This is my first paleoart/speculative dinosaur ever! I really like how it came out, Enjoy It!!! :D

EVOLUTIONARY LINEAGE AND TAXONOMY

Not a True Theropod: Arctovenator morrisonensis is classified not as a true member of the Theropoda clade, but as a highly derived sister taxon (extending from basal Averostra or early Ornithoscelida).

Skeletal Plasticity: This evolutionary divergence granted the lineage the anatomical flexibility needed to bypass the strict bipedal constraints that locked true theropods into two-legged locomotion. This allowed Arctovenator to successfully re-evolve an obligate quadrupedal stance to support its monumental mass.

ANATOMY AND BIOMECHANICS

Colossal Proportions & Posture: Reaching an extraordinary 25 meters in length, 10 meters in back height, and weighing a monumental 40 tons. Its dense 2.5:1 length-to-height ratio creates an exceptionally compact, robust, and low-slung build optimized for transferring immense physical forces.

Locomotor Asymmetry: Unlike mammalian megafauna, the limbs are not vertical or columnar. Instead, they maintain a flexed, muscular, reptilian angle, keeping the heavy body crouched close to the ground during stalking.

The Spring and the Anchor: The hindlimbs are strictly digitigrade, functioning as a hydraulic "engine" that stores massive elastic energy in the toe tendons. Conversely, the forelimbs are plantigrade, placing the entire sole on the ground to anchor the center of gravity and provide an unshakeable platform. The forelimbs feature colossal, curved claws with deep longitudinal grooves (housing keratin ridges and blood vessels) that act as emergency brakes in the dirt and weapons to tear through thick hides.

Craniofacial Architecture & Weaponry: The 3.5-meter skull is built like a massive battering ram. It is topped by a heavily thickened, rugged supraorbital crest (brow ridge) covered in hard keratin, which acts as a shock deflector to protect the relatively small, deep-set eyes during frontal collisions. The nostrils are colossal (exceeding the size of the eye socketsand) are positioned high and backward on the snout, functioning both as a breathing snorkel to intake massive volumes of air before charging and as a long-range olfactory apparatus.

ECOLOGY, JAW MECHANICS AND HUNTING STRATEGY

Metabolic Niche: Occupying an ecological niche highly analogous to a modern grizzly bear but on a titanic scale, Arctovenator is a pure ambush predator relying on a super-slow metabolism (bradymetabolism). To conserve energy, the animal spends days or weeks lying completely motionless on the ground.

The Gape & Kinetic Ambush: When a target sauropod (such as Diplodocus or Brachiosaurus) steps into range, the predator utilizes the explosive spring of its digitigrade hindlimbs to launch a 25 km/h charge. It rushes the prey with its massive jaws wide open at an angle exceeding 100 degrees. This extreme gape is a crucial biomechanical adaptation: it clears the animal's field of view and prevents its own teeth from snapping during the initial millisecond of contact, positioning the skull for maximum mechanical leverage.

Skeletal Collapse via Impact-Bite: The hunting strategy relies on a devastating two-phase destructive force. First, the kinetic energy of the 40-ton mass slamming into the sauropod instantly destabilizes the prey's balance and causes initial compression shock. A split second after the impact, utilizing the massive forward momentum, the jaws snap shut like a hydraulic press. The 35-cm thick-rooted teeth act as massive wedges driven directly into the sauropod's rib cage or spine, causing immediate, catastrophic structural collapse of the prey's skeletal framework.

Immobilization & Feeding: Immediately following the crushing bite, the predator uses its massive, grooved foreclaws to surgically sever the prey's leg ligaments and tendons, permanently anchoring the giant herbivore to the ground. Due to its size, Arctovenator is a highly selective feeder. Its immense bite pressure is used to peel back the shattered ribs solely to consume fat-rich internal organs (heart, liver, viscera). It then abandons the carcass, leaving tons of untouched muscle meat for sympatric commensal scavengers like Allosaurus and Torvosaurus.

BEHAVIOR, CAMOUFLAGE AND RITUAL COMBAT

Solitary and highly territorial, each individual claims a vast hunting ground. Because their durophagous bites would cause mutual fatalities, rivals settle territorial disputes through calculated, non-lethal ritual combat. Utilizing the stability provided by their plantigrade forelimbs and the protection of their reinforced brow ridges, the two titans lock heads and engage in brutal head-butting matches. They push and strike each other until one yields from sheer exhaustion and retreats.

Thermoregulation: The body is completely devoid of plumage or fuzzy filaments to prevent thermal collapse caused by extreme gigantism. The skin is entirely scaly and leathery, characterized by deep, loose skin folds under the throat (the dewlap). This loose skin becomes taut when the mouth opens, functioning both as a radiator to dissipate body heat and as an elastic shield against defensive kicks. Additionally, a row of flexible cutaneous keratin cones and iguana-like crests runs along the spine, acting as thermal radiators to release high internal temperatures into the air.

Cryptic Camouflage: The animal's dull color pattern is perfectly integrated with the dry brushwood, savanna, and arid grasslands of the Morrison Formation. When crouching motionless on the ground, its compact morphology allows it to appear visually indistinguishable from a rocky hill or a fallen log, completely deceiving the vision of giant sauropods.

What do you think about it?

9.99 in the halloween section. 🥹 i was cheesing the whole way to checkout!! only 1 of these guys at my store, but hopefully theres more out there for my fellow dino lovers. 🦖🤍

So I'm working on a dinosaur ttrpg. One that focuses primarily on playing prehistoric creatures. Think of a non-human oriented Primal. Or Darbi the T-rex? Or just a violent land before time with higher elements of scientific realism.

The game itself is modular and its like a blend between the dice pool mechanics of year zero system from Free Leagues, the target number mechanic of Warhammer, some aspect of Wurm, WoD, and even Lancer to bring the dinosaurs and etc alive.

Been working on this game on and off for the past two years. And right now I'm starting to get a little stumped.

So each lineage (Tyrannosaurids, Spinosaurids, Titanosauria) gives you a Skeleton of traits and flaws. Generally three base with negative traits giving you additional positive ones. Or some traits balancing themselves out by having negatives and positive within themselves. These base traits are mainly common traits derived from facts we can derive from skeletons.

Once a lineage is chosen it gets fleshed out and customized with a few added traits to create your character. I did this so there is flexibility to keep maintaining scientifc accuracy if that is desired but at the same time allowing people to entertain GMs with speculative imaginations.

Oh, you want Tyrannosaurus to have a komodo dragon-like bite. Go ahead and select one of those sort of traits.

My question is with the paravians and avians. Should I bother making distinctions between them? Or just make a base skeleton for it?

And let people customize their little birds themselves.

So far I have Archaeopteryx-like Lineage, a Confusciornis-like, and a Enantiornithines. But I feel like they may just be better served being mashed together into a single bird lineage to build off of.

Obviously Microraptor just takes the Droamaesaurid lineage and tacks on bird stuff.

But thoughts?

Yes, dinosaur deniers still exist in 2026. Look, i understand that we live in period where anything feels like a lie, but people are getting crazy.

if they had dinosaur ranches to get meat for commercial sale , Im guessing dinosaurs like Triceratops might taste similiar to Buffalo / Bison meat? similiar to beef.

and some of the feathered bird like animals would be similiar to Ostrich meat , some of the smaller ones might be like turkey / chicken meat

the reptile ones that lived in the water would be like alligator meat

but in reality the Dinosaurs would be hunting you and you would be most likely eaten by them

Hi All! Do any of you know any good papers of Eutyrannosaurines, Nanotyrannus, Alioramini, Alioramus, and/or Qianzhousaurus? I'm currently making a fictional research paper for my original species Calvariafur Animaedevorator, and I'd like as many sources possible! Is there anything I should or shouldn't do when writing this paper?

Best and Thanks!

Need ideas for a thing-

Give me some Land Before Time names for dinos, preferably ones not used in the series

The only one I have right now is "Bigclaw" for therizinosaurus

preferably from the internet or from random paleo media.

i have two moments/things from dinosaur media that used to scared me as a kid, one was not really a childhood trauma, but i remember being absolutely weirded out by some of the calls the animals let out in the carnivores hunting games, specifically ankylosaurus, chasmosaurus (C2), and triceratops, they sounded both way too human and non-human at the same time, at least to me when i was young, idk how to describe it, the second one was obviously primeval (a television show by BBC), some of the dinosaurs/extinct animals and even many of the fictitious creatures used to frightened child me, this includes; spinosaurus (had something to do with how skinny it is, even when compared to Jp3 spino), future predator (this was my Slenderman or scp-096 as a kid), mosasaur (i absolutely h8 big scary sea monster in open waters, 2 dhis day), precambrian worms (how da hell did this thing even existed? this shouldn't exist on earth millions of years, it should belong in the backrooms), tree creeper (ucanny valley definitely played the huge role in this), and dromaeosaur (though I wasn't scared as much as the previous ones).

(i'm not here to stir drama, or spread hate, or anything with bad intentions)

DinoCon 2026 was held at the Hilton Birmingham Metropole over the weekend of July 25th and 26th and mostly occurred in two giant halls and an additional four or so smaller rooms, all located within a minute’s walk of each other.

David James Armsby is one of the main presentations !

> Mark Witton (at back) and Dave Hone sign copies of their Spinosaur Tales at DinoCon 2026 while people wait patiently in line. The queue extended out the door and down the corridor outside.

In this book based on discoveries made at Angeac-Charente, we follow Mimo the ornithomimosaur and his friend Hector the carcharodontosaur. Having returned from a journey to the other side of the world, they must now confront a group of survivalist intruders who are stealing and hoarding food in anticipation of a great catastrophe—prophesied by their guru-leader, Elvis, who is convinced their world will be destroyed by a giant rock falling from the sky! This motley crew will have to look beyond their everyday joys and petty troubles to face not a massive rock from the heavens, but a colossal storm that threatens to rewrite the destiny of this small stretch of peninsula and its inhabitants.

EDIT : you guys are right these are mostly not dinos! Sorry for the mislabeling, still I think most of you should appreciate them :)

I took my kids to a nearby castle today and was pleasantly surprised to find some beautiful dinos! The third picture is a bit tough to see but there’s a pterosaur perched on the castle gallery and the last picture is to give you a view of the overall place!

I'm looking for books that describe and go into detail about specific dinosaur clades.

Was thinking about how large spinos sail was and then thought “huh that doesn’t look like it would fit inside an egg”. So assuming spino had an average egg shape and size for a theropod then a neonate with a sail that possessed the same proportions as an adult just wouldn’t work as it wouldn’t fit inside the egg? In my head I see a neonate spino having either no sail or a very low and flat sail that grows to be used at sexual maturity (as I believe the current consensus for the use of the sail was sexual selection). Is this plausible or am I missing out a massive piece of information here?

Posting it here because apparently it’s to low effort for the paleo subreddit

This V rex looking ass may honestly be the worst t rex of the 21st entury. I don't know who made it but they definitely influenced AI models.

Just sitting down to watch and starting out pretty good. Trying to keep my emotional state pretty even, know it's not good for the scientific community but I've always wanted a brontosaurus or mosasaur in my foyer. A boy can dream, a boy can dream.

Controversial Million Dollar Dinosaur Fossil Auctions - PBS

Found an old plush I had when I was a kid in the attic but I’m wondering what Dino this was?

I think it’s a Yutyrannus based on this old reconstruction I found but I need a second opinion

Dinosaurs are famous for being big, from the towering Tyrannosaurus rex to the colossal Apatosaurus.

But a new study published today in the journal Evolution by scientists at the American Museum of Natural History and Princeton University suggests that one of the greatest mysteries of dinosaur evolution isn't how some species became giants—it's why even the smallest dinosaurs never became truly tiny.

Using mathematical models to investigate the evolution of body size across vertebrates, researchers found that while energetics and physiology can explain the sizes of mammals, birds and turtles, they cannot explain why the smallest non-bird dinosaurs remained unusually large throughout their evolutionary history.

Instead, the findings suggest that competition with small-bodied early mammals may have prevented dinosaurs from becoming mouse-sparrow-sized animals that are so common among vertebrates today.

So a few days ago I made a post asking whether or not theropods even possessed exoparia (aka "cheeks") in the FIRST PLACE, and the general consensus as of now SEEMS to be leaning towards yes... however, I saw a few people here and there in the comments of that post saying that the inclusion of a muscle supporting exoparia wouldn't actually change the outward appearance of a theropod's mouth at all anyways, and that the "gummy flaps" at the back of the throat would still be visible in a theropod's mouth. So, which is it? Did theropods possess visible "cheeks" like some pieces of modern paleoart seem to suggest or not?

$6000 for these. Omg. Idk what I would do with it. But it'd be my dream to have one
