Fossil Remains of Proterosuchian from The Panchet Formation, Damodar Valley of India

Fossils of proterosuchians are known from the Early Triassic beds of many different countries like China, Russia, South Africa and India. Remains of the earliest described proterosuchian Ankistrodon indicus, are known from the Lower Triassic beds of the Panchet Formation of India. Later, the genus was renamed as Chasmatosaurus indicus. Chasmatosaurus is now considered as a junior synonym of Proterosuchus. The Early Triassic archosauromorph remains from India are based on rare and poorly preserved proterosuchian jawbones, few vertebrae and an ilium. This article reports the discovery of additional Proterosuchus fossil material, humerus and rediscovery of the cervical and caudal vertebrae from the Lower Triassic beds of the Panchet Formation, from the locality near Asansol district, West Bengal, India. Proterosuchus humerus has not been described before from India; hence this additional material along with axial materials that are a cervical vertebra and a caudal vertebra will add further information about this Early Triassic proterosuchidae of India.
