Integrative phylogenomics reveals a Permian origin of Adephaga beetles

“…excluding fossils described by Ponomarenko (1977)) from the Late Jurassic to Early Cretaceous whose phylogenetic relationships remain unclear (Beutel et al ., 2013). Recently, several well‐preserved fossils kept intact in Burmese amber have been described and could be assigned with comparative accuracy to extant tribes or even genera (Liu et al ., 2015; Kataev et al ., 2019; Beutel et al ., 2020a). These new discoveries, combined with more robust phylogenies, push back the age of these derived lineages, thereby resulting in older estimates for the crown of the family.…”

New Genus and Species of Limnichines from the Cretaceous Amber of Myanmar and Taxonomic Notes on the Family Limnichidae (Coleoptera, Polyphaga)

“…According to the traditional interpretation [ 10 ], the probable Cenomanian radiometric age of Burmese amber has been estimated as taken from sedimentary beds, indicating that it had been re-deposited. Much of the resin is rolled and bored by pholadid bivalves, which demonstrates that the resin was hard before it was buried [ 11 ]; the centers of the resin pieces, however, were still soft when bored, so the formation of the amber is considered to be contemporaneous with the deposition of the bed [ 12 , 13 , 14 ]. Thus, the age of this amber still remains unclear, although an enormous concentration of amber with inclusions in certain geological layers gives evidence that its deposition occurred under peculiar conditions and during a definite term.…”
