Stenopelix, also known as Stenopelix valdensis, was known to inhabit present-day Germany and the fossil was found near Buckeberg, Harrle in a sandstone quarry in the Wealden Formation. No information is available about the types of habitat that these dinosaurs used to inhabit.

The reproduction used to take place through the sexual way, where the males used to deposit sperm inside the female body and the females then used to lay fertilized eggs, that had developing embryos inside them. The

The Stenopelix skeleton that was discovered was in a bad condition and was quite fragmentary, thus, no information is available about the physical appearance and features. The fossil that was discovered also lacked the Stenopelix skull.

Their diet was considered to be herbivorous. Stenopelix size is estimated to be around 59 in (150 cm).

The generic name of this species is derived from two Greek words, 'stenos' meaning 'narrow', and 'pelyx' meaning 'pelvis', and thus, roughly translated to 'narrow pelvis' and the specific name is kept in the reference of the Wealden Formation.

It is known to have been reviewed by Sues and Galton, too. There has been confusion around it belonging to the Pachycephalosaurs or Marginocephalia, while a phylogenetic position and record from the lower cretaceous stated Stenopelix valdensis to be an ornithischia.

It is quite fascinating to discover about the basal ceratopsians from the early cretaceous and if you are interested, read about Chaoyangsaurus and Liaoceratops, too.

Did you know...

The type species is known as Stenopelix valdensis.

It is known to have lived in the Berriasian Stage, that is, around 140 million years ago.

The fossil specimen has been described based on a fragmentary and almost complete (partial) skeleton preserved that had the skull absent.

It was known to be originally part of the Max Ballerstedt collection, which was, preserved in Bückeburg Gymnasium Adolfinum. It was later, around 1976 moved to Georg-August-Universität Göttingen in the Geowissenschaftliches Zentrum der Universität Göttingen collection.

The classification of the Stenopelix is debatable as there has never been a skull found.

The cladistic analysis by Paul Sereno is known to have stated that this species belonged to Pachycephalosaurs, while Richard Butler and Robert Sullivan considered it to be Marginocephalia and before Butler and Sullivan, it was known to have been reviewed by Sues and Galton.

The phylogenetic position and early fossil record from the Lower Cretaceous stated Stenopelix valdensis to be an Ornithischia from the Wealden of northwestern Germany.

The hollows of the discovered basal ceratopsians served as a natural mold in order to study and analyze this possible small ornithischian dinosaur.

Why are they called Stenopelix?

The generic name Stenopelix means 'narrow pelvis' and it is believed that this dinosaur might have had a narrow pelvis as suggested by the fossil remains.

It is not known who discovered this dinosaur fossil, but Stenopelix valdensis was named by Christian Erich Hermann von Meyer.
