    Lepidosauromorphs and associated vertebrate fauna from the Late Triassic Tiki Formation, South Rewa, Gondwana basin, India: implication for paleoenvironment and paleobiogeography
    (Springer Nature, 2023-03-27T00:00:00) Singh, Y. Priyananda; Sharma, K. Milankumar; Tiwari, Raghavendra Prasad; Patnaik, Rajeev; Singh, Nongmaithem Amardas; Singh, Ningthoujam Premjit
    Tiki Formation is well known for the presence of rich vertebrate fossil assemblages including archosaurians, cynodonts, xenacanthids, hybodonts and actinopterygians in the Gondwana succession of India. Here, we report indeterminate Sphenodontia and indeterminate Lepidosauromorpha from the Late Triassic Tiki Formation. The presently reported early diverging lepidosauromorphs might have fed on small invertebrates and small vertebrates/insects. The presence of early diverging lepidosauromorphs from the Tiki Formation extends their geographic range from Europe, N. America and S. America to the Indian sub-continent during the Late Triassic Period. Further, the reports of archosauromorph assemblages and the aquatic vertebrates from the Tiki Formation have strengthened the idea of affinities of vertebrate assemblages between Laurasia and Gondwana sub-continents of the Pangea. � 2023, Indian National Science Academy.

    Phytosaurian Osteoderms From The Late Triassic Tiki Formation (Shahdol District, Madhya Pradesh), India
    (The Palaeontological Society of India, 2015) Sharma, K. Milankumar; Kumar, Jitendra
    The Late Triassic fossiliferous deposits of the Tiki Fomation of the South Rewa Gondwana Basin of India, is well known for its vertebrate fossil assemblages including temnospondyl tetrapods, archosauroform rhynchosaur, and several crurotarsans such as phytosaurs and rauisuchids. The present paper describes some phytosaurid osteoderm remains for the ?rst time from the Tiki Formation. These osteoderms are found together with phytosaurian teeth, jaw and vertebrae. On the basis of their texture, shape, size, morphology and association with phytosaurian remains, the present specimens have been assigned to phytosaurids
