Systematics

First constructed in 2000, it was considered to include Notosuchus, Libycosuchus, and Sebecosuchia.[1][2] In a 2004 phylogenetic study, it was defined as the most recent common ancestor of Notosuchus, Libycosuchus, and Baurusuchoidea and all of its descendants.[3]

Ziphosuchia is often considered to be the sister group of Neosuchia, a clade that includes modern crocodilians. Razanandrongobe is the oldest representative of this clade.[4]

gollark: No clue, this is hard.
gollark: Anyway. A replay attack could happen if your system encrypts "open the door" as, say, "a" constantly and "close the door" as "b" constantly. While the message is technically secure in that they can't arbitrarily encrypt a value, if someone wants to open the door they can just send "a".
gollark: Yep!
gollark: Still no.
gollark: You mean the protocol argument passed to rednet.send? No.
