The Loneliness of Isauria.


Following my visit to Mexico, Ricardo Servín Pichardo‘s reconstruction of Isauria (Latirhinus uistlani) from Formación del  Cerro del Pueblo, Parras, Coahuila brought  to the fore the amount of pathologies previously described in much detail by  Angel Alejandro Ramírez Velasco. According to Angel’s thesis (Patologías Oseas en Dinosaurios Mexicanos; un Estudio Comparativo. México 2013),  Isauria survived a lesion (congenital or fracture) to  the left hand, that fused two metacarpals and distorted the hand but at the end healed.

But finally, the real reason Isauria   died  was of the injuries to his right leg, a fracture that in time deformed the fibula and shin bone,  generating a new pathological “hooked bone” and a tendonitis that made it drag its leg until the animal finally could not move, could not eat or drink. A phenomenon observed also in modern birds.Microsoft Word - TESIS MAESTRÍA COMPLETO 8

I envisaged the first artwork as Isauria laying down with scavengers and predators awaiting its slow demise… but I decided instead of depicting the lonely death of a dinosaur in the shores of an inner sea or river.dsc01776latirhinus-copy

Here’s a new version of the previously blogged image… with further corrections by Ricardo and Angel.

The Extended 2016 Mexican Palaeontology Experience…


Remember this?Coahuilaceratops B

In a previous blog entry I named Kritosaurus its main protagonist , but its true real brand new name is Isauria (Latirhinus uitslaniand) is currently in the vaults of the wonderful, “classic” among classics,  Museo de Geología in Mexico City on its way to be delivered to UNIVERSUM, a popular interactive museum (mostly for the young generations) dedicated to science and technology also in Mexico City… who knows, maybe one day it could also be a guest of honour in our forthcoming Mexican Dinosaurs exhibition in Monterrey?

This mount of Isauria is the painstaking reconstructive labour of Ricardo  Servín Pichardo,  Palseontology student of René Hernández, that dedicated many hours  to model  the missing bones  and refurbish the broken ones of this very famous Mexican hadrosaur,  first featured  incomplete in the Geology Museum back on the 90’s with the skull magnificently reconstructed by the also famous paleoartist Marco Antonio Pineda

Look at the wonderful way the forefeet are reconstructed. Delicate, precise and accurate  in the posture while preserving some evident  pathologies!


This only makes evident that Mexican Palaeontology’s got real talent that deserves to be supported and promoted as much as possible!

The Isauria experience was far from the only event…I gave a double talk  at René’s class at  UNAM and  presented some new Mexican dinosaurs artwork like this “Sabinosaurio” for the first time in public.sabino-copy

The main event (200 + people) was at UNIVERSUM with the talk Bringing Dinosaurs Back To Life (AKA Reviviendo Dinosaurios). Following the talk I was happy to present, together with René Hernández, awards  for some budding paleoartists  I must give special thanks to master craftsman Jorge A Ortiz Mendieta and Ruben MP (Rexisto)  for a wonderful Oviraptor present…!

It was no coincidence that there was an exhibition at UNIVERSUM that was also called “Reviviendo a los Dinoaurios” featuring artwork by several Mexican paleoratists including  Fomisaurios by Aldebarán (Aldo) Castañeda.  René was responsible for having my artwork also extensively featured.

Here with fellow conspirators  Angel Ramírez, Carmen Naranjo, Ricardo Servín Pichardo and René Hernández and so many students and dinofans ... thanks to everybody once again for their dedication, appreciation, hospitality, and most of all… great conversation!

To cap it all… Party with Aldo’s famous fomisaurs (taylor made to my colour wishes)!!. including a beer-drinking Labocania and hairy heterodontosaurus!)…farewell until, hopefully,  next year!

Early Jurassic Rewind… Extreme Mexican dinosaurs?!

Heter9Mexico copy

Just a few scraps of Early Jurassic dinosaurs have been found in the Huizachal Canyon, Tamaulipas, Mexico… but thanks to the work of among others  David Fastovsky, René Hernández and Angel Ramírez what is clear now is that among them were Heterodontosaurs and Coelophysids... I have taken this opportunity to fiddle with the current “new look” of heterodontosaurs after Chinese and South African discoveries (Pegomastax et al)… and I must admit I was amazed by the wonderful, artful and  over the top reconstruction of Tianyulong in the new exhibition at the American Museum of Natural History in NY, that has taken care to vindicate early ornithischians forever… so I started to think: what could I do to go more extreme than that? After all this was Mexico! What if a really angry heterodontosaur in full display would have a modern porcupine pale by comparison… fangs added to the threatening show?

Heterodontosaurus might have been a small animal, but Coelophysis would have to think twice to try to take a bite. Please note that based on what little we know of Early Jurassic  Mexico, the reconstructions here are merely speculative, specially in regards to the detail… both animals appearances are  based on what we know from others.Who says Palaeontology can’t have a sense of humour… even as deadly serious as this is?Hetero Rage copy

The Mexican Dinosaur Eden(Part 1)

Coahuilaceratops B

As I was mentioning in the previous blog, even as fragmentary as the fossil material is most of the time in Mexico, the Cuenca de Parras, Coahuila, specifically this time  Cerro del Pueblo in the north of Mexico, has produced exceptional specimens like  the  chasmosaurine  Coahuilaceratops here, with their thick, enormous horns that shared space with Kritosaurus herds, one of the first Mexican dinosaurs I saw on display  at the Museo de Geología, although given that the research was still not complete (and is still isn’t) the name may change any minute!.

This is a typical North American dinosaur 72 million year old semi-coastal landscape and you can appreciate the complexity of the mural, long time in the making! … even with Trödontids courting in the foreground (we know only teeth, but they were there for sure). For a change I’ve tried to avoid theropod-onithopod confrontation! But that won’t be the case in the next one…Coahuilacaretops is also going to be a prominent protagonist of the forthcoming Dinosaur rEvolution event… mostly thanks to Robert Gaston‘s excellent sizeable cast that will be featured in it! More to come…

Working on another Mexican enigma…

Parras BLOGDuring one of my visits to vaults of the Museo de Geología, one of the fossils that impressed me most was this (still unnamed) hadrosaur muzzle and beak.  Still partly encased in the stone matrix, it gave me a truly realistic image of an almost perfectly preserved, recently deceased animal. Wish I had a cast!ParrasB Muzzle

It is not until now (after my consultations with René Hernández and Angel Ramírez that I decided to have a go to it and rehearse some new colour patterns… I know some people will find the patterns over the top, but I still find the somewhat believable. After all a hippopotamus  has bright pink zones of its body… and most definitively doesn’t have colours vision (as I asume all dinosaurs had!…)

This hadrosaur has been located in Parras, Coahuila and is similar to Edmontosaurus, and probably  7.6 meters long.. The rest of the skeleton has not been found. Still it is a beauty and has a lot of character!

More for Parras still to come… Parras, Coahuila is also known as the Mexican Dinosaur Eden!

Cretaceous México: Magnapaulia.

Mexico! BMore than a  decade ago I was at the entrails of  the Instituto de Geologia Museum in Mexico City and René Hernández was laying on my lap an enormous and very heavy femur head of a gigantic hadrosaur. The  size was so impressive that it could have been mistaken for an Apatosaurus! But no, it was yet another gigantic lambeosaur found by René’s team in the north of Mexico, land of  army clashes with the cartel… even in those days. Scientists trying to excavate in Saltillo or Coahuila have to deal with the terrible scourge of that horrifying “war on drugs” that has been  Mexico’s disease for so many years, to do their work.

Nevertheless… the search has continued unabated… I had to pay tribute to the Mexican palaeontological teams efforts and  some of those immense lambosaurine hadrosaurs from Mexico… this time in the shape of of a herd of Magnapaulia being chased by some Albertosaurus … I have used a familiar scenario from another old project that never quite congealed in my eyes… so I modified the scenario and finished it thanks to the help (again) of Angel Ramírez (that was very specific about the kind of flowery, Magnolia semi tropical vegetation) and René Hernández himself, I have come to a final product that I am more or less satisfied with. There’s always room for improvement!

Note the crest of Magnapaulia (still mostly hypothetical, but based on the fragmentary remains we have) and the very tall hip spines, so characteristic of all these Mexican hadrosaurs. There are more murals to come in the next weeks…
