North America

Ever since Tyrannosaurus mcraeensis was described, I've seen some people not mentioning it as a valid species, while some hate it being on art instead of Tyrannosaurus rex, and some of you calling it Mcraetyrannus instead.

So, I ask again, why is this species hated so much by Dinopedia?

Is it because it makes Tyrannosaurus rex less unique? Is it because Tyrannosaurus imperator or Tyrannosaurus regina should've been named instead? Honestly, those two are kind of just whiny points, so I legit want to know.

In a scene for the Jurassic World Novel I'm writing, there's a scene where an injured Tyrannosaurus mcraeensis (which is a real species, it's just new) and Ankylosaurus magniventris fight. It starts with the Ankylosaurus swinging its club tail, which the Tyrannosaurus (nick named "Boss") dodges. Boss roars at it (with an accurate call) before trying to bite the tail. The Ankylosaurus bellows in agony and frees its tail from Boss and then slams its club into Boss' shoulder, fracturing it and causing his arm to cripple and fall limp. The Boss then roars blood on the Ankylosaurus before tipping it over like a turtle. (And due to this portrayal of the species, the back is flat, aside from the spikes in the sides) The Ankylosaurus squirms and flails before Boss puts his foot full force over the Ankylosaurus' ribs. A loud crunch is heard and the Ankylosaurus immediately dies.

How accurate is this scene?

Solotocephalosuchus

In 1934, two Dutch paleontologists were digging and excavating along the Angola-Mediterranean coast, near the Kem-Kem beds. Soon after, Coronosaurus aferocanis (The Crowned Lizard of Africa) was named. C. aferocanis was a species of large Cenozoic archosaur during the early Neogene period. It was thought that it was about 4.6 feet tall and an impressive 16.7 feet long, however, recent fossils along the Mediterranean of more fossils reveal this was, in fact, not a bipedal, saurischian Archosaur, but instead a basal crocodylian.

The species was reclassed to Solotocephalosuchus angolii, (Sun-Headed Crocodile of Angola) and has been found in coasts all along the Mediterranean. Its name stems from the “crown” of three osteoderms along the back of the head that sort of form a sun. A lower osteoderm on either cheek also helped this allusion. It is likely that Solotocephalosuchus hunter in freshwater marshes, using its habitat to blend in as it got close to its prey.

Little indents found on the neotype’s humerus and fragmented femur (PIMUZ 6 783) suggests robust muscle connection that we believe was used to chase down prey quickly on land. Specimen PIMUZ 7 438 also has a preserved forelimb, with sharp claws likely used to grip wood to get in and out of water, and of course pin prey on marsh floor and drown them. A fossil found on July 3rd, 1967 found a Solotocephalosuchus’ stomach ripped open by predators, but it was found that its lungs, identifiable by slight grooves in the rock, were relatively large, and indicated it could likely go a long while without air, perhaps longer than modern crocodiles.

Due to Solotocephalosuchus being slightly fragmented, and one of the only creatures found in this specific formation, it is unknown its prey and predators, however, from its thin conical teeth and sharp claws, it has been inferred that it ate and hunted aquatic or semi-aquatic fauna. Its predators are unknown, but some believe the ravaged specimen was from another Solotocephalosuchus.

It has been theorized, however never had any solid backing, that males would enter stand-offs through rearing up, using their tail as support while they roared/snarled at competitors, using their thick, hypothetical throat pouches to reach deep tones. Some believe that they were social to all, others believe they were social to only species with a close genetic and emotional bond, while others believe they were hostile to anything but mates. Due to CAT scans of the skull, we know that they were socially capable of any of them.

Due to it being very close to Ceratosuchus burdoshi, the two have been classed under Ceratosuchinae, a subfamily of horned crocodylians, which is related to Voay robustus and Crocodylus rhombifer.

In 1976, the previously mentioned specimens, PIMUZ 6 783 and PIMUZ 7 438, were bought by PIMUZ, and were transported to Switzerland in 1978.

In the late 1980s, a dig site in Panama proved worthwhile when they found a formation which was thought to be a massive Miocene marsh. In it, several fossils of turtle and mammal species were found, along with a Solotocephalosuchus specimen. This was a little bit larger and more terrestrial than its African brothers. It was proved to be of the same genus after a hard battle with other paleontologists over “Andre”, PIMUZ 3 489.

Andre was officially accepted as a valid species (Solotocephalosuchus panamensii) in June of 2001, and was transported to PIMUZ along with their other species. Since then, more and more specimens are found of S. panamensii and S. angolii every year.

I recently created a map showing the distribution of Lystrosaurus in Lopingian and Early Triassic. Having completed the creation, I thought about where else these animals could live and where, in theory, they could be found in the future?

As can be seen from finds in the southern hemisphere, these animals lived around the subrolar region, where suitable vegetation probably grew and where the last relict lakes from the Karoo Ice Age probably remained (South Africa, India, East Antarctica). In the northern hemisphere, they also lived near the subpolar region (western Russia, northwestern China), where similar climatic conditions were probably observed, but due to the proximity of the ocean, especially between Siberia and Eastern Europe (on some maps, the authors show a sea strait between these regions, but this is unlikely, because there was already a land connection between Europe and China). So, taking into account the already known places of discoveries, I imagined the habitat zone of Lystrosaurus in Early Triassic (purple) and marked with "˅" places where they most likely lived and where we are likely to find their fossils in the future:

1) Southern part of South America (Chile, Argentina). ~250 Ma, it was located not far from South Africa and, most likely, the animals could get there by land.

2) East Africa (Tanzania, Kenya and other countries). Location located between South Africa and India. I believe the likelihood of finding a Lystrosaurus fossil there is very high.

3) Northern Europe (Norway, Sweden, Finland). This region was not separated by sea and mountains from Eastern Europe.

4) Finally, the territories located between Eastern Europe and China: western Siberia, southern Siberia and Mongolia.

However, you noticed that there are still no finds of Lystrosaurus skeletons from the equatorial part of Pangaea, right? There is no doubt that they lived there, and it is a matter of time before we find them there. I marked "?" suggested places where Lystrosaurus might have lived, but the certainty is not so high. Since scientists believe that El Niño in Panthalassa occurred at the Permian-Triassic boundary, the climate on the western coasts was likely drier than on the eastern. The same thing is observed today: the driest deserts are located in the west of Australia, South America and sub-equatorial Africa. For this reason, I believe that Lystrosaurus lived mainly in the east of Pangea, on the coast of Tethys. Here are the proposed locations:

1) Australia. It was located by south of Tethys and probably had similar conditions to India and Antarctica.

2) New Guinea. It was probably connected to Australia.

3) Eastern territories in central Pangaea: northeastern Africa, Arabia, southern Mediterranean, northern Africa, Spain and eastern North America.

4) Greenland. This region was located in northern latitudes, not far from modern Europe.

5) South China. There is a high probability that it was connected to Northern China.

What do you think about it? Can we really find Lystrosaurus there, or did they inhabit a smaller area?

A cattle rancher in Texas heard a loud slam in his pasture in the middle of the night, so he got up, put on some clothes, and grabbed his flashlight and a double-barrel shotgun. Once outside, he noticed a spot in the pasture where his cattle weren't going, so he checked in out. The cold rustle of wet leaves and grass from the rain crunched under his feet as the light of his flashlight cut through the night like a hot blade. Once he made it to the area, he noticed it.

A bull, no less than 24 months old, lying dead, a massive wound tearing at its side. Wasn't coyotes, and he's never found wolves, so what killed it? He studied the carcass, the wounds were fresh, meaning whatever just killed his stud, was still out there. "Show yourself!" The rancher yelled out into the forest. A single, high-pitched click responded. Then a loud snap, and a snarl. "I know you're out there!" He called out again. This time, multiple clicks and snarls replied, and then the forest floor was littered with bright, shining green eyes, all closing in.

The rancher panicked, raising his shotgun and firing into the forest. Loud snarls, hisses, and clicks responded, and the animals began to walk out of the darkness slowly. They were long, the rancher estimated them to be around 12 feet long, and 6 feet tall. It had two nasal crests that shined. He has never seen this animal before. Bipedal, long, nocturnal, possibly a pack hunter, the rancher's heart began to beat so fast it felt as if it was skipping a beat. The animal before him snarled, then began to run for the rancher. It leaped onto the paddock fence and then made a low chirping noise, which drew out the others.

The lead animal fell to all fours, its long arms providing extra support as it walked across the fence. Behind him, the rancher saw his perimeter fence, barbed, double-wound chain-link, cracking and creaking, meaning more to come. Then he remembered something his dad told him; "Your enemies are only strong with the body if you are weak in the head." The rancher wielded the shotgun and blasted the animal on the fence, dropping it into his pasture. But the animal just got up. It limped for a second and shook its body, and the rancher could hear the two shells dropping onto the floor.

The animal let out a snarly hiss, and the other animals behind the fence broke it open, lunging for the rancher. He swung the shotgun, smacking the animal away with the end of the gun. "Back, foul creatures of the night! I am not afraid!!" The rancher yelled out. He then saw all the eyes and counted in his head. 42 eyes. 21 animals.

The coos of owls in the distance almost felt as if they were mocking his predicament. A loud snapping noise brought him back, and he saw the lead only three feet from his face. The rancher swung with all of his might, striking the lead, and seeing it crashing down. He couldn't see it, but he felt the cold blood drip to his hand. He made a blunt injury. Suddenly, one of the animals to his left pounced tackling the rancher to the floor and slicing his back open. The rancher let out a yell of agony, as his back became a fighting ground for competing animals.

The rancher barely grabbed his gun, and swung, striking one above him. He momentarily scared them away, through swinging the gun and yelling, and he limped back to his house. He immediately locked the door limped to his phone on the wall, and dialed 9-1-1.

"911, what's your emergency?" The operator asked. "My pasture is being under attack from a weird chupacabra dinosaur pterodactyl, I don't know what the fuck it is, but *coughs heavily and spits blood*, I'm wounded, my cattle are in danger, please hurry!" He explained. The operator sounded taken aback. "Alright, help is on the way, try and stay with me, what can you identify about them?" She asked. "6 feet tall, 12 feet long, they, *coughs* have bullet resistant skin, and there's 21 of them." The rancher explained.

"Are you in need of medical services?" The operator asked. "Yes, my back has been ripped open, I can barely walk or stand." The rancher explained. "Okay, my name is Rosi, I'm gonna stay on the line with you until help arrives, can you tell me your name?" The operator asked. "Henry, Henry Van Janick." The rancher replied. "Alright, Henry, do you have any evidence of these animals besides your wounds?" Rosi asked. "Yes, I have their blood on my shotgun." Henry coughed.

Suddenly, he heard a loud clang on the wall, then the creaking of his window, and finally a loud smash. Broken glass littered the floor and the animals snarled and hissed, trying to get inside. "Henry, what was that?" Rosi asked. "It's them! They're breaking the windows to get inside!" Henry yelled. "Alright, stay calm, help is almost there," Rosi informed. One of the animals broke through the window and pounced. "No! No! No, no! ARGHH!!!" Henry let out a shriveled shriek as a loud snarl, crash, and crunch was heard over the line. Rosi covered her mouth with her hand as she listened to the animal feed.

Why? Because I want to reconstruct depictions of each of those dinosaurs like I did the Rex.
