Lirainosaurus? Not so big, then.

Yes, the landmass he life on was not big enough for Giants like Argentionsaurus.

Ah, European islands....
casearutena's avatar
Yes of course, but the island on which lived this titanosaur was one of the largest of the European archipelago. It was large enough (at least three times the size of Madagascar) to allow the presence of many different titanosaurs (several are yet unnamed), some large (~ 20 m). This island was sometimes connected to other smaller European island and also with Gondwanan and Laurasian landmasses. That's why we find in a same region both dwarf and large species belonging to a same group and also species with Asian (ex. hadrosauroids) and African (ex. an unnamed new Abelisaurid genus) affinities.

Could this abelisaur be close to the dubious Tarascosaurus? Or even the Tarascosaurus itself? And I did read on the Paleo-King Blogspot about some supergiant titanosaurs from France, some while back, rivaling things like Puertasaurus and Argentinosaurus. COuld they have lived on this large island?

The new abelisaur specimen is most probably a distinct form than Tarascosaurus. The age of the latter is Lower Campanian, the new genus is younger and dates at least from the Late Campanian. The preserved elements of Tarascosaurus (a proximal femur and incomplete vertebrae, two dorsal and one caudal) belong to a 3-4 m long animal. The new form is 5-6 m long and it is very similar to Majungasaurus (according to an abstract paper, this specimen shares also with Rugops some primitive characters). I don’t know how many bones were found (I’ve only seen photos of a few bones), but the material includes at least a partial skull, several teeth, some hind limb elements and caudal vertebrae (and all the bones are well preserved).

The giant sauropod from Angeac is Lower Cretaceous (Hauterivian-Barremian) and lived probably on a larger mainland than the Late Cretaceous Ibero-Occitan Island. This giant is represented for the moment by limb bones, vertebrae, teeth, and the affinity of these remains are uncertain, the bones seem belonging to a titanosauriform (but not necessarily a titanosaur), whereas the spatulate teeth (such as these: [link] [link] [link] [link]) are reminiscent of turiasaurians (a group unknown in Hauterivian-Barremian deposits) but this shape of teeth is maybe simply a morphological convergence. The discovery of the Angeac site is very recent, the second excavation campaign is planned this summer and he'll have to wait few years before a better understanding of this giant sauropod. The same site has also already yielded numerous remains (cranial and postcranial) of a new ornithomimosaur. A very small area of the quarry has been excavated and an agreement with the operator of the quarry, guaranteed the access to the site (which covers several hectares and extends beyond to the quarry) for 15 years. The extension of the excavation beyond the quarry is also planned in the future.

So lots of unnamed animals from that part of Europe, is it? And how old exactly is the Ibero-Occitan Island?
casearutena's avatar
The Ibero-Occitan Island is Campanian-Maastrichtian.

During this time interval, the geography of this island had probably varied and it is possible that at certain times it is divided into two islands (Iberia and Occitan) and that at other times it is integrated parts of Central Europe.

Ah, so it was a changeable island, was it?

Very nice !

How long to make your drawings? And what is your technique?
Hyrotrioskjan's avatar
HyrotrioskjanProfessional General Artist
For this piece I take 4 hours.
2 for the drawing with pencils and and 2 with Photoshop Elements for color and shading.
The next will be the Ampelosaurus.
Teratophoneus's avatar
cool, Ampelosaurus ist ein recht eindrucksvoller dinosaurier, vor allem wegen des stacheligen rückenpanzers. Machst du auch Histriasaurus-den rebbachisaurier aus Istrien?
Hyrotrioskjan's avatar
HyrotrioskjanProfessional General Artist
Histriasaurus stammt aus der frühen Kreide, ich nehme jetzt aber erst mal nur Dinosaurier (und ein Pterosaurier =) ) aus dem späten Campanium und dem Masstrichtum.
Es kommen noch:
Arenysaurus
Atsinganosaurus
Pararahbdodon
Blasisaurus
Balaur

Ampelosaurus wird der größte Dino dieser Reihe sein

cool, auch wenn mir die ersten 2 gattungen bis jetzn ich bekannt waren :D
