Well, as with all worlds, a mass extinction has to happen someday. But this wasn't a naturally caused extinction. The aliens who made this world in the first place decided to hurl a 3km meteor at the center of the supercontinent. The results were catastrophic on wildlife all across the world.
Casualties:
LITHOHYRACOIDEA
euhyracoglires: 57% of species extinct
hyracocervia: 79% of species extinct
hyracomarina: 100% extinct.
rhinohyraxia: 98% of species extinct.
ALLOHYRACOIDEA
lagohyraxia: 48% of species extinct
SUBCLADE HYRACOCARNIVORIFORMES
hyracoinsectiphila: 80% of species extinct (less specialized species were able to live)
volaticonectiphagia: 94% of species extinct (less specialized species with a brand-new adaptation explained in era 2 causes this clade to live.)
SUBCLADE HYRACOCARNIVORA
cynohyraxia: 20% of species extinct (very generalized group, was able to survive with minimal damage.)
hyailuria: 30% of species extinct (a little more specialized, but overall, an intact clade)
Notes:
- it seems like the more specialized lithohyracoids are struggling. will they survive the next extinction event?
- hyracocarnivoriformes is the most intact hyrax clade.
- lagohyraxia might become the top herbivores?
