Profile Name: Puertasaurus reuili Length: 38 meters Mass: 110 tons When: Late Cretaceous, Maastrichtian, 70 milion years ago Where: South America Classification: Animalia, Chordata, Reptilia, Saurischia, Sauropodomorpha, Titanosauria, Titanosauroidae, Lognkosauria, Puertasaurus, Puertasaurus reuli
Puertasaurus reuili is a genus of Sauropoda lived in what is now South America, about 70 million years ago. Almost 40 meters long and weighing more than 100 tons, it could be the largest dinosaur ever existed, probably even longer and heavier than its more famous cousin, Argentinosaurus, although there are other claimants in North America. It is a dinosaur only recently discovered, and described in 2005. Unfortunately, his remains are very partial: it has only one spine (incomplete) with some vertebrae of impressive size (1.06 meters high, 1.68 meters wide), and rib cage had to be very large (5 to 8 meters wide) , and this would make it probably the widest dinosaur ever. From a single cervical vertebra note, it is understood that this dinosaur had a neck long and stocky, unusual feature in sauropods.

I would better use NimaÂ´s reconstruction. It is far better than that one (short, stubby neck, legs too long, torso too short). IÂ´d also better give a range of ~30-40m. It is not certain whether it is larger than A. huinculensis, even tough I too think so. The vertebra are wider, with a greater surface in anterior or posterior view, however not as tall, with a flatter, wider centrum.
Hammerhead: I’m planning on watching the new “65” movie that’s coming out in March. I don’t expect it to be scientifically accurate for the most part but I do think it’ll be fun.

Supercommunist: There are also cases of fish trained tricks, there appear to be more species of fish that can use tools compared to reptiles, and fish like moray eels and groupers are capable of interspecies cooperation.

Hammerhead: I would say about equal intelligence or give fish a slight edge.

Supercommunist: Any idea on which group of animals is more intelligent in general, fish or non-avian reptiles? I used to think that reptiles had the advantage but I noticed that there actually appears to be a lot more literature on fish intelligence so I am having doubts.
