While it has some aspects of YKINMK, there are at least a few concrete biological charges.
(Disclaimer: I am no Trojanhorse; I don't know animal biology nearly as well as she did/does, so anything I say should be verified with research. That said, I've obviously got some idea what I'm talking about, just not a veterinarian's level.)
Firstly, while it's theoretically possible that female dinosaurs had vaginas similar to those of mammals, it's unlikely, as no known reptiles or birds (the two "ends" of dinosaur evolution) have them. It's impossible to know for sure, since soft tissues don't fossilize, but I feel this fic's explicit naming of the Veloci Deinonychus' reproductive organ as a vagina is incorrect. Amphibians don't have vaginas either, so the frog DNA wouldn't help explain their presence. Not that it explains their lack of feathers or incorrect size for Velociraptor either, lazy stupi
On a much broader note, any animal in a stressful situation, like being in an unfamiliar environment with no visible means of escape (the transport container) is very likely to lash out at something that has it cornered, but they're certainly not going to switch to mating mode this quickly, especially not with an organism outside their species. (Some animals with very group-oriented social structures, like, squirrel monkeys, do use mating as stress relief, but that's generally when a perceived danger has passed, and they feel sheltered within their group dynamic again. Raptor dinosaurs may very well have had complex group socialization like that, but they wouldn't gain a calming feeling from an unfamiliar creature not their species.)
Random thing I just noticed: The fic refers to its raptors as Velociraptor Antirrhopus, which is an old, defunct classification for what is now called Deinonychus antirrhopus. Not necessarily a charge, considering how the Jurassic Park films have permanently confused the planet as to what Velociraptor really looked like, but I wanted to mention it.
Now, for something a bit more opinionated: There are clearly a handful of fetishes in here, but the one I have an issue with is the bestiality. Because animals are not sentient, they are not capable of giving consent; therefore, I consider any usage of animals in a sexual activity to be animal abuse. Even a fictional extinct animal that eats the human partner at the end. Obviously, as a person literally paid to protect animals, I'm possibly more bothered by this than most, but I couldn't discuss this story without bringing that up.
Finally, let's look at Muldoon. (Movieverse here, as it's been too long since I read the novel to discuss it properly.) Obviously, any shipping/smutty/fetish story can potentially add details to a character's personality to make the scenario possible. However, in this case, one of movie!Muldoon's very distinct traits has been lost: His canon self is very much a protective figure towards other characters. He's basically in charge of safety on Isla Nublar; he tried to save the other worker who got grabbed in the movie's opening scene; he left himself exposed in the open to cover Dr. Satler's run for the maintenance bunker, which got him killed, but led to all of the remaining (after that point) characters surviving. In this fic, Muldoon leaves another person in mortal peril just for his own personal gratification. That's a level of out-of-character beyond the basic pornfic, I think.
Sorry, this is probably way more than you wanted, but it's not often one of the badfic threads has a fandom I actually care about, so I wanted to way in. So in short, I do think there's enough here for a mission. Then again, I've only written three myself, so what do I know? :)
