Little fun fact, when suggesting this composition to Joschua, part of the idea was that a recent study found resonance chambers in Caipirasuchus, which further ties into improved hearing in baurusuchids, which might suggest that these animals were a lot more sound-based

Not the most complete, but nonetheless great to see the notosuchian record of Africa expanded
