If Ivantosaurus is now classed as an adult Eotitanosuchus why is Eotitanosuchus described as being only 2-3m long?

While I know nothing about this animal/these animals, I think the 2-3 m long estimate is quite straightforwardly an estimate that was done before Ivantosaurus' inclusion and still cited because it is the only (or best) estimate available.

Do you guys think there could have been any fossil animals that had cognitive abilities on par with those of today's exceptionally smart animals (e.g. dolphins, corvids, parrots, elephants, and primates)? You know, other than fossil representatives of the aforementioned animals?

I'm sure extinct hominids and their earlier ancestors were anywhere from equivalent to today's primates, to far smarter. Neanderthals, for example, were probably near or on par with modern humans intellectually. While homo erectus might have "only" been on par with chimps/gorillas, etc. I would imagine their descendants or branch cousins surpassed today's primates intellectually as evidenced by much more advanced tool use.
As to marine life, I think prehistoric whales may have been quite intelligent. No way of knowing, but I bet ancestors of orcas, squalodons, Livyatan, Brygmopheseter, and probably some extinct baleen whales were intelligent. But it's difficult to compare with modern orcas and dolphins. BTW, pinnipeds are also very intelligent, people tend to forget about them.

I said to exclude close fossil relatives of modern primates, cetaeans, etc.

Many maniraptorans, probably. Seeing how intelligent birds can be (crows are not far from apes and dolphins), this is quite plausible. Other than that, I'm not sure. Cephalopods show that intelligence doesn't have to strictly follow phylogeny (as they are hardly related to the classical examples of intelligent animals), so there may have been intelligent fossil creatures of which we have no clue how intelligent they were.

One can only wonder about the intelligence of extinct cephalopod lineages, but they did go through remarkable radiations and had a vast diversity compared to modern cephalopods, so (just hypothetically) some extinct taxa may have been very intelligent. And is there more data on extinct therapsids by any chance? elosha11: Do you mean Australophithecus? Homo erectus reached endocranial volumes in the range of modern Homo sapiens, used fire, created stone tools well beyond the capacity of most modern people to make and populated large parts of Asia until a few tens of thousands of years ago. |

Could you tell me how pinniped intelligence compares with that of say, dolphins, primates, etc.? Are they in the same ballpark as these creatures? |

Are marsupials really less intelligent than placentals on a general basis?

Ask any animal related questions here I want to ask something about dogs --- I have seen many times my dog eating ice and I am really worried about my little one. What should I do to stop him from taking ice? |
