The Lost Files- Stegosaurus by HodariNundu The Lost Files- Stegosaurus by HodariNundu
JURASSIC PARK Los Archivos Perdidos

Epoca: Jurásico tardio, hace 140-150 millones de años
Distribucion: Norteamerica y Europa
Longitud: Hasta 12 metros
Peso: 6 toneladas
Dieta: Herbivoro
Stegosaurus es uno de los herbivoros mejor protegidos. La doble hilera de placas pentagonales en su dorso le hace parecer mucho aun mas grande de lo que en realidad es, pero su verdadera arma son las mortales púas de su cola, que puede manejar con increible habilidad para defenderse.
La cola del Stegosaurus es inusualmente flexible de modo que puede golpear a depredadores de cualquier tamaño y en cualquier direccion. Normalmente es un animal pacifico que vive en grupos familiares pequeños. Suele merodear por las zonas boscosas con agua abundante, y es raro encontrarlo en campo abierto.
Los Stegosaurus jovenes se quedan varios años con sus padres; a veces, los hermanos mayores ayudan a cuidar a los pequeños. Los Stegosaurus jovenes son vulnerables a los ataques de depredadores como los raptores, pero pueden lanzar una llamada de alarma muy caracteristica que causa una reaccion defensiva inmediata en cualquier Stegosaurus adulto que ronde cerca.
Los grupos de Stegosaurus son nomadas y no tienen territorios definidos. Una de las caracteristicas más inusuales del Stegosaurus es su larga lengua de color azul. Esta lengua es prensil y puede manipular objetos con cierta presición.
TRIVIA: Los estudios veterinarios demostraron una inusual actividad en el nódulo nervioso cerca de las caderas del Stegosaurus. El veterinario en jefe de Jurassic Park estaba convencido de que el Stegosaurus realmente tenia dos cerebros funcionales, pero no pudo comprobarlo, ya que el incidente en Nublar impidió que se llevaran a cabo mas estudios.


Age: Late Jurassic, 140-150 mya
Range: North America and Europe
Length: Up to 12 meters
Weight: 6 tons
Diet: Herbivore
Stegosaurus is one of the best protected herbivores; the double row of pentagonal plates running down its back make it look even bigger than it really is, but its main weapon are the lethal spikes on its tail, that Stegosaurus can use with incredible skill.
Stegosaurus' tail is unusually flexible, so it can strike predators of any size and in any direction. Usually, it is a peaceful animal that lives in small family groups. It roams around forested areas with plenty of water, and it is rare to see it in the open.
Young Stegosaurus stay with their parents for several years; sometimes, older siblings help taking care of the young. Young Stegosaurus are vulnerable to the attack of predators such as raptors, but they can produce a very distinctive alarm call that causes an immediate deffensive reaction from any adult Stegosaurus nearby.
Stegosaurus herds are nomadic, and have no defined territory. One of the most unusual traits of Stegosaurus is its long, blue tongue. This tongue is prehensile and can manipulate objects with some degree of precision.
TRIVIA: Veterinary studies demonstrated an unusual activity in the nervous node near the hips of Stegosaurus. The chief vet in Jurassic Park was convinced that Stegosaurus really had two functional brains, but he never got the chance to prove it, for the incident in Nublar prevented any more studies from taking place.

The node ending isn't really a brain, it's a source of highly packed tissues!!! Correct me if I'm wrong!!!!

Hey HodariNundu, I think you should explain how the stegos aren't wiped out from the raptors.

Why should they? Stegos are huge, well armed and travel in herds...

What I'm saying here is that scientists believed that stegosurus' extinction was caused not just by herbivorous rivals, but by new predators, like the raptors. Stegosaurs are more armed against something huge, like t-rex. But, I have a theory on how they thrived.

Well... don´t think that makes a lot of sense. Stegosaurs coexisted with many predators smaller than Allosaurus or Torvosaurus (Marshosaurus and Stokesosaurus, to mention a couple) for millions of years, and according to some scientists, raptors were probably around at the end of the Jurassic anyway. Stegosaurs survived up to the early Cretaceous in some parts of the world. Also, now we know that the plates were probably not defensive; the main weapon was the thagomizer, the spikes in the tail. Had raptors been an important influence on Stegosaur evolution, we could expect the early Cretaceous stegosaurs to be better armed than their Jurassic counterparts, but they are not. And last but not least, many stegosaurs were very large, heavy animals. I don´t think there were many raptor species willing to risk their lives by attacking a dangerous stegosaur with so many easier prey around.

But it's just my opinion.
