I once found one on the south side of easy island. Watch out though. Therinzo and spinos are waiting over there. Went over there with lvl 5 pterodactyl and then found both by the same area. It’s very scary over there but I brought a ton of eggs so I can eat.
These guys are harmless and seem to hang around the swamps or near the edges of the redwood biome.
They die faster than parasaurs, but will escape much easier. Swift attacks from a carnivore or a strong headshot will take them down before they run.
Use a bola to stop it dead in its tracks, use a tranq darts with a longneck rifle and aim for the head. The headshots do way more damage. When taming this dino pay very close attention to its torpore timer. It has about a 3 and a half minutes of torpor. Use demetrodon kibble for the highest level, but crops or mejoberryies is good as well. If you want a very quick tame lookup on youtube a really cool stimberry trick (Look up Ark Stimberry Taming). This trick is good if you want a fast taming dino, but its difficult to do with this dino because of its little torpor timer.
