> What happen if we eliminate crocs and akins (and turtles, tortoises > and terrapins) - Crocodylia or Loricata?
I'm not sure I understand the question. "Loricata" has been used for several groups (including crocodylians) but is now generally used for armadillos, I think. Eliminate them from what?
Crocodylia+Testudines clade (some genetic study place Testudines as an archosaur taxon - syster to Crocodylia).
When they say extant, what if the group goes extinct?
Ah, thanks!
You're welcome.
