Rare Allosaurus fragilis mandible, U.S.A. (Wyoming), Jurassic (150 million years old), length 40 cm, with base
note: Allosaurus was one of the main predators of the Upper Jurassic and stood at the top of the food chain. It is estimated to have reached a height of 12 metres and weighed in at several tonnes. Its jaw was equipped with long, narrow, serrated teeth that made this dinosaur an effective killing machine.
This mandible was discovered in Wyoming in the middle of a cluster of other dinosaurs. The allosaurus was probably a victim of scavengers after its death and its remains were scattered. It is very rare to find such an isolated piece.

Condition report

Mandibule d'Allosaurus: Découverte en 2015 dans le Red Fork Ranch, proche de Kaycee dans le Wyoming. Elle a été préparée en 2017 seulement. La raison est liée au fait que le propriétaire voulait attendre de voir s'il trouvait d'autres morceaux pour reconstruire un crâne complet. Heureusement pour nous, ce ne fut pas le cas. La mandibule était comprimée et plusieurs dents étaient tombées de leur logement. C'est quelque chose de très courant et normal dans le processus de fossilisation. Les dents ont cependant été retrouvées dans le bloc matricielle qui contenait la mandibule.
