Stygimoloch and Pachycephalosaurus are often considered distinct species, but there is ongoing debate among paleontologists regarding their classification. Some researchers argue that Stygimoloch may represent a juvenile form of Pachycephalosaurus, given similarities in skull structure and features. However, others maintain that they are separate species based on differences in size and morphology. Ultimately, further research and fossil evidence are needed to clarify their relationship.
Baby pachycephalosaurus were hatched from eggs laid by their parents. The parents would create nests to protect the eggs until they hatched. Once they hatched, the baby pachycephalosaurus were on their own to fend for themselves.
maybe all species have the same karyotype;/
A group of closely related species would share the same genus.
Organisms of the same species can mate and produce offspring.
They are members of the same species.
Stygimoloch was created in 1983.

Stygimoloch
cuz there were no humans around at the same time as dinosaurs
Pachycephalosaurus would win, it could easily slam the Velociraptors to the ground.
Yes, pachycephalosaurus is a noun, a singular, common, concrete noun; a word for an extinct dinosaur, a word for a thing.
It WAS a type of dinosaur that lived about 65 million years ago.
Baby pachycephalosaurus were hatched from eggs laid by their parents. The parents would create nests to protect the eggs until they hatched. Once they hatched, the baby pachycephalosaurus were on their own to fend for themselves.
caves and swamps
Probably not
Pachycephalosaurus is a genus of pachycephalosaurid dinosaurs. The type species, P. wyomingensis, is the only known species. It lived during the Late Cretaceous Period of what is now North America.
There are both Pachycephalosaurs
