Ticinosuchus is an extinct genus of suchian archosaur from the Middle Triassic (Anisian - Ladinian) of Switzerland and Italy.[1]
Description
One of only a handful of fossil reptiles that have been found in Switzerland, Ticinosuchus (meaning "Ticino crocodile" due to its origin from the Swiss canton Ticino) was about 3 metres (10 ft) long, and its whole body, even the belly, was covered in thick, armoured scutes. These scutes were sometimes considered to have been staggered, alternating between several rows.[2] However, some studies refute this claim, instead purporting that the scutes were aligned in neat rows, with a one-to-one assignment of scutes to vertebrae.[3] The structure of the hips shows that its legs were placed under the body almost vertically. Coupled with the development of a calcaneus and a specialized ankle joint, this would have made Ticinosuchus a fast runner, unlike most earlier reptiles.[4] Ticinosuchus is thought to be very close to or possible even the same species that made the Cheirotherium trace fossils found in Germany. It too shows a narrow track-way, similar to that of Ticinosuchus. It is one of the most famous fossils of Besano.[5]
Fish scales have been preserved in the abdomen of the specimen. This was likely indicative of a piscivorous diet.[6] Ticinosuchus shares many similarities with paracrocodylomorphs, such as certain adaptations of the ischium[1] and possibly (but not certainly) hyposphene-hypantrum articulations.[7][8]
