1- Inspired by a #jurassicpark talk with friends so reposting what I said here, I'm going to make this an atypical what if. "What if the Lost World had Giganotosaurus?". As in, replacing T.rex with Giga without it being JP3/JWD styled derision on Tyranno. Art by @TheTokuSociety
2- The aim here is to present something new without it just being escalation. Now timing wise this might be tricky, as Giganoto was only revealed a few years prior. However, this recency might make it more likely to happen. Design likely would resemble the Gunrey illustration.

In the Hell Creek, no. Only place T.rex and Alamo *maybe* crossed paths was the North Horn formation, and even then only mildly. And yes, Tarbo has been found to prey on sauropods both with diet and tooth marks. Tarbo had more serrated teeth & likely could open its mouth wider

There are places Alamosaurus and Tyrannosaurus mighta crossed paths, but they preferred different habitats so it be a bit like a gorilla meeting a white rhino. Chance encounters than habitual cohabitation. Nemegt formation for Tarbo meanwhile had higher numbers of large herbs.

Carnosaur thread - Bite Smarter, Not Harder

To quickly clarify, Carnosauria is a group whose members are in a bit of flux. There is ongoing debate on if some like spinosaurs count as being included, so I'm going to just focus on Allosauroids as everyone agrees they're carnosaurs 2-
Carnosaur is a 1993 mockbuster horror film extremely loosely based on an actually decent 1984 novel by John Brosnan, in which the film threw out the ahead-of-their-time bird-like dinosaurs and starred only low budget versions of coelurosaurs, Deinonychus and Tyrannosaurus-

Ceratopsian Horn thread a.k.a "How to use your head", Part 2

Ceratopsians were, largely speaking, living in groups (though it varied in size), were smaller than most of their predators, and likely would much rather run or intimidate than fight. 2-
The horn styles and shapes vary so much because different ceratopsians used them on their own kin in different ways. Some might have jousted, some locked horns and wrestled, some rammed each other's flanks, and some likely didn't do much intraspecies combat at all.

Ceratopsian Horn thread a.k.a "How to use your head", Part 1

Doing another speculative biology run, and on one of my favorites no less. Ceratopsians are easily one of the "Big Six" archetypal dinosaurs which show up in almost all ensemble media, and there's little shock why. 2-
North American Paleontology has been a cornerstone of the field since the late 1800s, and the horn-heads are one of the most prolific and diverse looking dinosaurs on the continent. However, they have been subject to a bit of the 'same hat syndrome' I discussed raptor having.

1- Raptor thread
Speculative evolution n has long been a facet of Paleontology, longer than most would think. It's inevitable when one discusses lifeforms no living eyes have seen. The difference between speculations past vs present, is the degree of being grounded 2 -
Nowadays a lot of things are corrected about Dromaeosaurids. A lot of sources get the feathers right, they get the wings right, the claws are stabbing weapons and not slashing tools, and they all look like giant, toothy hawks. So what's the problem here?
