He was able to identify the mushroom down to its specific family and concluded that it represented a genus not known before.

However, Currie (1980) found it to represent a new and distinct genus which he named Acerosodontosaurus.

However, there has been no official description of the remains and the name cannot be used until scientific scrutiny suggests they represent a separate genus.

Although it represents a distinct genus, a generic name has not yet been proposed for "C." acer.

Their larvae were originally believed to represent a distinct genus (Macristium) and even family.

In 1988 referred to Paronychodon lacustris, they were later considered diagnostic enough for them to represent a distinct genus and species.

They agreed that this must represent at least a new species, and perhaps a whole new genus, which is the more inclusive classification of life.

Since then, it has been recognized that these two species form a natural, monophyletic grouping and were suggested to represent a new, undescribed genus.

Only after careful analysis did the scientists conclude that the nearly complete skull and partial jaw represented a completely different genus and species.

It was given the name Halitherses grimaldii, and represents a new genus.
