The procoptodon is a very useful creature in many ways
1. It's very fast on land, not so much in the water though.
2. It's jump is very useful (especially in Scorched Earth).
3. It can carry babies for transportation if needed.
4. A female Procoptodon gives an imprinting boost but only when it's mate boosted.
5. It deals decent damage and can push attackers back a good distance, especially small creatures like raptors and pegos.
6. Very good Rare mushroom and berry collector.
7. It's pouch is a passenger seat.
8. Pressing R3 will put a baby in the pouch but also take the baby out if needed.
