Sanpasaurus imperfectus by HodariNundu Sanpasaurus imperfectus by HodariNundu
Un "Sanpasaurus" imperfectus, reconstruido como un escelidosaurio gigante.
En realidad, el nombre "Sanpasaurus" corresponde a un sauropodo; la especie "imperfectus" consiste en un esqueleto incompleto de un dinosaurio ornitisquio, con patas similares a las de un iguanodonte.
Junto con estos restos se hallaron espinas similares a las de un estegosaurio que podrían pertenecer al mismo animal.
La idea de que "Sanpasaurus" imperfectus pudiera ser un escelidosaurio gigante de formidables espinas no es mía; le debo la inspiración a Rexisto, artista gráfico y paleo- de este blog: [link]
Sea cual fuese la verdadera identidad de "Sanpasaurus" imperfectus, un escelidosaurio gigante parece ser la mejor explicación para algunas huellas de gran tamaño que datan del Jurásico inferior, por lo que no pudieron haber sido hechas por iguanodontes o hadrosaurios.
(Primer "S. imperfectus" en DA)

A "Sanpasaurus" imperfectus, depicted as a giant scelidosaur.
In reality, the name "Sanpasaurus" belongs to a sauropod; species "imperfectus" has no genus name yet and consists on a very incomplete skeleton of an ornitischian dinosaur, with legs very similar to those of an iguanodont. Along with these remains, weird, long stegosaur-like spikes were found, which could belong to the same dinosaur.
The concept of "Sanpasaurus" imperfectus as a giant scelidosaur with formidable spikes is not mine; I owe the inspiration to Rexisto, graphic artist and paleo buff from this blog: [link]

Whatever the real identity of "Sanpasaurus" imperfectus was, a giant scelidosaur seems to be the best explanation for some fossil footprints from the Early Jurassic, which couldn´t have been made by iguanodonts or hadrosaurs.

According to what I've seen, I don't think Sanpasaurus was a real dinosaur.

Well that's a no brainer. No one's seen a dinosaur and it's pretty likely no one ever will. But I was saying that based on what I pictured the bones to be. It just seems like an unorganized heap of fossil fragments. But unless we can bypass time paradoxes, many of our hypotheses can never be fully proven. So either one of us could be wrong here.

Saludos HodariNundu, gracias por ilustrar y citar mi teoría. Estoy revisando los huesos y las huellas correspondientes a este animal y es posible que reciba un nombre nuevo. Si bien es de menor tamaño que lo estimado en un principio, ya que al tener una tibia de 60 cm tendría un fémur ligeramente mayor pero no de 1 metro, como suele suceder en lo animales bípedos. Me han gustado las púas que le has puesto, revisaré bien las mismas para darme una mejor idea....

This drawing makes no sense. If you think "S." imperfectus was a scelidosaurid, why did you give it an iguanodont face and a saurischian pelvis?

Judging by the scale I drew inspiration from, about 3 meters tall, not sure about the length tho. It's all highly speculative to this point.

:iconjason244555:
Jason244555 Featured By Owner Feb 21, 2011
Still speculative or not, 3 meters all is pretty big for such an animal (Scelidosaurs were a lot smaller than this). Speaking along these lines, I had recently heard of an Allosaurus sized type of Ceratosaurus. Have you heard of this creature? If so, do you know what the species name is (I think the common Ceratosaurs species was nausicornis)?
Also, Mexico seems to be a rising hotbed of paleontological discoveries lately, I wonder what will come up next.

:iconhodarinundu:
HodariNundu Featured By Owner Feb 21, 2011   General Artist
Yeah, it's Ceratosaurus ingens, from Africa. There's only teeth, though, as far as I know, but if it is indeed a ceratosaur, it could be as large as Tarbosaurus!

And yes, Mexico still has many new discoveries to offer... two bad I can count active Mexican paleontologists with the fingers of one hand...

That is amazing about the Ceratosaurus Ingens. Along these same lines, have you heard of (or know anything about)Aliwalia? There have been mixed reports of this potential giant Herrerasaurid dating to the Carnian stage somewhere in Africa. I have heard that its remains were mixed in with Eucemencesaurus (I don't think I even came close to spelling that one right), but a large jawbone (possibly Herrerasaurid like?) was found in the remains that certainly did not belong to any kind of known prosauropod. There has been speculation that this early carnosaur could have been up to 38 feet long, which could have made it the most dangerous land animal of its time. I am very unversed on the whole Aliwalia debate, and was wondering what your opinion is, on this very mysterious and controversial beast.

:iconhodarinundu:
HodariNundu Featured By Owner Feb 21, 2011   General Artist
Yeah, unfortunately Aliwalia rex as we knew it is no longer valid. The jaw is obviously from a predator but not necessarily a dinosaur; could be some other kind of archosaur (a rauisuchian, perhaps?).
Either way, it seems that it was not as large as once believed.

Parece el hijo de un iguanodon con un anquilosaurio... igual no me cuadra que tenga tanto peso en la cola para ser un bipedo, eso no haria que se desbalanceara muy cabron a la hora de caminar?

It is a speculative reconstruction of a real but very fragmentary dinosaur.

Depending on where this animal was found, I say that the fossils found to make people think of this animal are actually fossils of several different Dinosaurs found in the same spot due to a flood or a similar force of nature. What do you think?

:iconhodarinundu:
HodariNundu Featured By Owner Feb 21, 2011   General Artist
"Sanpasaurus" fossils do belong to two different dinosaurs, a sauropod and an ornitischian.

Damn, this is a crazy looking thing. Tianyulong had feathers, but this guy clearly took a one-eighty with evolutionary decor. If it wasn't in such a jumbled state, it may have been considered the coolest discovery yet. And are those two Dilophosaurus hunting Yandusaurus?

Yes, they are Dilophosaurus... but I don´t know what the little guys are (maybe a little bit too old to be Yandusaurus)
