Dinosaurs became entrapped in the cohesive and adhesive mud as they drank and hunted near the floodpond. The preserved fauna consists of almost all dinosaurs with the majority being carnivorous dinosaurs including Allosaurus (material from at least 44 individuals make up almost 67% of all remains), Torvosaurus (1), Ceratosaurus (1), Stokesosaurus (2), Marshosaurus (2), and possibly an Ornitholestes. Herbivorous dinosaurs include Camarasaurus (5), Haplocanthosaurus (1), Barosaurus (1), Amphicoelias (1), Mongolosaurus (1), an unidentified sauropod, Camptosaurus (5), Stegosaurus (4), a possible ankylosaur (1), and an unidentified ornithopod. Non-dinosaurian fauna include a crocodile (Goniopholis), 2 turtles (Glyptops), 4 genera of gastropoda (snails), and 4 genera of charophyte.
