It is among the few geological formations outside of Russia, South Africa, and China that documents the recovery of global ecosystems immediately after the Permian-Triassic extinction. It shares similar traits to some of these other formations, including the dominance of Lystrosaurus and the primary predators being proterosuchid reptiles. It also preserves a diversity of temnospondyl amphibians.{{Cite journal |last1=Ezcurra |first1=Martín D. |last2=Bandyopadhyay |first2=Saswati |last3=Sengupta |first3=Dhurjati P. |last4=Sen |first4=Kasturi |last5=Sennikov |first5=Andrey G. |last6=Sookias |first6=Roland B. |last7=Nesbitt |first7=Sterling J. |last8=Butler |first8=Richard J. |date=25 October 2023 |title=A new archosauriform species from the Panchet Formation of India and the diversification of Proterosuchidae after the end-Permian mass extinction |journal=Royal Society Open Science |language=en |volume=10 |issue=10 |doi=10.1098/rsos.230387 |issn=2054-5703 |pmc=10598453 |pmid=37885992}}{{Cite journal |last1=Ezcurra |first1=Martín D. |last2=Bandyopadhyay |first2=Saswati |last3=Sen |first3=Kasturi |date=March 2022 |title=A new faunistic component of the Lower Triassic Panchet Formation of India increases the continental non-archosauromorph neodiapsid record in the aftermath of the end-Permian mass extinction |url=https://www.cambridge.org/core/journals/journal-of-paleontology/article/abs/new-faunistic-component-of-the-lower-triassic-panchet-formation-of-india-increases-the-continental-nonarchosauromorph-neodiapsid-record-in-the-aftermath-of-the-endpermian-mass-extinction/22B9B38A22AD12C16E82E228F6F017E4 |journal=Journal of Paleontology |language=en |volume=96 |issue=2 |pages=428–438 |doi=10.1017/jpa.2021.100 |issn=0022-3360|url-access=subscription }}
