Ferenceratops

Although ceratopsian dinosaurs were widespread around the northern continents during the Cretaceous, for a long time they appeared to have been completely absent from Europe. A few possible fragments were found – but their identification as ceratopsians was highly disputed, with some paleontologists instead identifying the remains as belonging to ornithopods.

But this year some new fossils have given more support to the ceratopsian interpretation, suggesting that a whole diverse European branch of these dinosaurs was there the whole time. They’d just been misidentified as rhabdodontids due to the convergent anatomy of their teeth, jaws, and limbs.

One of these newly-recognized ceratopsians was Ferenceratops shqiperorum (previously known as Zalmoxes shqiperorum), which lived during the late Cretaceous (~72-66 million years ago) on the subtropical Hațeg Island, in the region of what is now Romania

It was a small species, about 2m long (6’6″), and seems to have lacked the elaborate frills and horns seen in many other ceratopsians, despite being closely related to both protoceratopsids and stem-ceratopsids.

Its new genus name references Ferenc, the birth name of Baron Franz Nopcsa, the gay Transylvanian paleobiologist-adventurer-spy who originally found some of its fossil remains.

Island Weirdness #06 – Zalmoxes robustus

Hațeg Island was home to quite a few unique species right at the end of the Cretaceous, so we’ll be focusing on it for a few more days.

Zalmoxes robusutus was a member of the rhabdodontids, a group of herbivorous ornithopod dinosaurs related to well-known names like Iguanodon, Tenontosaurus, and the hadrosaurs.

It had a chunkier build than its closest relatives, with a deep skull, a large beak, and a rotund body. Like other rhabdodontids it would have had powerful jaw muscles and ridged cheek teeth specialized for scissoring, adaptations for cutting up particularly tough plant matter.

It was also quite small, about 2.4m long (7’10”), although since the largest known fossils represent subadults this may not have been its full size. A second species in the same genus (Zalmoxes shqiperorum) lived on the same island and was actually slightly bigger, suggesting that Z. robustus represented a minor case of insular dwarfism.
