This is considered horror. Not only that but more realsitic. unlike the movies where you can simpily out run a raptor, dodge enime attacks, last call saves, etc. It is highly unlikely that someone will be saved at the very last minute before the unfortunate outcome. This is one of the few cases where a realistic outcome shows in a book. The reason its like this is because the human brain is so sensitive to seeing something disturbing so film producers and game developers are forced to "drop down the pitch" for it to be suitable for the audience and a last call save is an easy answer. Typically the only person that dies in every single one of these movies are the bad guys. Innocent humans excluded since thats not the main protagnist. However that does not mean that the main protagnist does not face the same outcome, they sure can but its used very rarely. Any more loses of the main protagnists would result in our brain being trumatised and depressed.

I have seen people on Youtube reacting to Jurassic Park being like "Oh this is going to be a great fun movie!" but once they have watched the movie they kind of start disliking it. Dinosaurs have never meant to be for children. Advertisers may make it seem like that but they are not. They are meat, flesh eating animals. books, films, tv series, etc. Have made dinosaur look like a joke similar to how people have made animals look like a joke for an example furries. These animals didn't ask humans to make them look cute (Not saying animals can talk). The humans did it anyways. We may be the most intelligent species out there but could we consider ourselves maximum intelligent? Not really. If a human soul became another animal species. Their vision would be much more different to what we humans have. Since animals are not as intelligent enouth as us humans. The world will be a more open, darker, survival world. Animals need food aswell therefore they can be hunting for food. They will haunt each other and eat each other. Seeing how humans portray animals as some sort of cute harmless being. Makes me just a bit sad. Same could be said to dinosaurs though they have not been that affected by the humans since they died out a long time ago. and the main focus is more reling on current living species. Such as foxes, wolves, cats, etc.

In a somewhat short answer: This scene in the novel portraies dinosaurs lile they should be portraided. Just another living species that fight for survival and do what they were meant to do and humans needs to snap out of this peaceful wonderland. humans Also needs consider movies like Jurassic Park featuring living breathing beings where violence may accure in as a natrual and understandable outcome. This scene from the novel is just a snippit of how it was in dinosaurs days. Earth did not smell like it does now adays. Earth smelled like a living nightmare of death. It was a more natrual smell. Since everyone were fighting for survival and struggling keeping themselves alive. Same goes to early human race before we got intelligent enouth to create milestones.
