That's right, this time, there's not just one, but TWO new dinosaurs, described in the same study.

The first one isn't a new genus, but a new species of *Pinacosaurus*, *P. hilwitnorum*, the second one, is actually a new genus, *Eopinacosaurus mephistocephalus*, which is also related to *Pinacosaurus*, as it was originally described under that genus in 1999.

The generic name for "Eopinacosaurus" means "Dawn pinacosaurus", being a clear reference to the genus to which this animal once belonged. The specific name on the other hand, on this case, "mephistocephalus" refers to the combination of "Mephistopheles", due to the devil-like horns on its head.

As for *P. hilwitnorum*, it's specific name, "hilwitnorum", is the combination of the names of Robert Hill, Larry Witmer and Mark Norell.

The name is *Laueropterus vitriolus*, it is an monofenestratan from the Late Jurassic (Tithonian) of Germany. It is known from the Mörnsheim Formation, with the material assigned to it being a partial skeleton discovered in 2007.

The generic name (name of the genus), on this case, "Laueropterus", means "Lauer's wing", in honor of René and Bruce Lauer, who helped making the fossils of many animals in southern Germany available for studies. The specific name (name of the species) on the other hand, "vitriolus", means "acid", due to the texture of the holotype, which looks as if the bones were being dissolved.

This animal was a early monofenestratan, being a somewhat large animal for its time, with a wingspan of roughly 1 meter (3.3 ft).
