In Depth Togocetus is a genus of primitive whale that was first discovered in a phosphate mine that is early Eocene in age. Togocetus is noted for being similar to genera such as Protocetus and Pappocetus. Further Reading - A new archaeocete and other marine mammals (Cetacea and Sirenia) from lower middle Eocene phosphate deposits … Read more
In Depth Not much is known about Mahajangasuchus, but the robust skull suggests a strong bite force even for a crocodile. The teeth of Mahajangasuchus were also conical and fairly blunt suggesting that they were used on larger prey like land animals rather than small prey like fish. Mahajangasuchus has been moved around quite a … Read more
In Depth Sinornithoides is a genus of small troodontid dinosaur that lived in China during the early Cretaceous. The holotype individual of this genus, a subadult, was found in a nesting position with its head tucked under its left arm, very similar to how another small troodontid named Mei was found. This may indicate that … Read more
In Depth The superficial morphology of Milleretta is that of a modern lizard with an array of sharp teeth suited for work on insects. Milleretta is considered an anapsid on the basis that the skull has no openings behind the eye socket. Early study of the skull did reveal two depressions at the back of … Read more
In Depth Not many fossilised bones of this dinosaur are known, but those that are are simply huge. Comparing these bones to the more complete remains of other genera has resulted in very rough estimates of around thirty meters long, raising the probability that Ruyangosaurus was one of the largest animals to ever walk the … Read more
In Depth Although details are uncertain, Kutchicetus is noted as being a small remingtonocetid whale (relative of Remingtonocetus). The tail of Kutchicetus seems to have been quite well developed and may have played a more important role in swimming than other primitive whales, though there is no evidence that a tail fluke had been developed. … Read more
In Depth Janenschia is a genus of titanosaur that has a classification history closely tied to the African diplodocid sauropod Torneria and by extension the North American Barosaurus and the English Gigantosaurus. We start in England in 1869 when Harry Govier Seeley named Gigantosaurus based upon a few vertebrae, partial limb bones and an osteoderm. … Read more
In Depth Though described from a lower jaw, Pappocetus has been identified as distinct from other protocetid whales by the presence of a stepped notch on the underside of the jaw. Further Reading - A description of new species of zeuglodont and of leathery turtle from the Eocene of Southern Nigeria. - Proceedings of the … Read more
