Coccinelloid beetles have a sparse fossil record in the Mesozoic. Here, we describe and illustrate an unusual coccinelloid beetle, gen. et sp. nov., from mid-Cretaceous Kachin amber. stands out within the Coccinelloidea due to its notched profemora and the presence of antennal grooves on the elytral epipleura. Based on our phylogenetic analyses, we suggest that is most likely related to the family Anamorphidae. The alternative placements are critically evaluated based on our comparison of the morphology.

Increased sampling reveals the complex evolution of sauropod dinosaur tooth replacement rates.

Unlike most herbivores, sauropod dinosaurs evolved simple teeth that were replaced rapidly. Sauropod craniodental morphology is conserved relative to that of many archosaur clades, but tooth breadth and replacement rate vary substantially. Two neosauropod clades, Titanosauria and Diplodocoidea, independently evolved both narrow-crowned teeth and high tooth replacement rates among a suite of other convergent features.

Article Synopsis
  • Tenebrionoids are found in late Mesozoic ambers, but their diversity is not well-studied due to unclear family classifications.
  • Researchers describe a new tenebrionoid beetle from mid-Cretaceous Kachin amber, highlighting its unique pronotal sulcus and tarsi.
  • This beetle is tentatively classified in the Pythidae family, marking it as the first fossil from this family discovered in the Mesozoic era.

The Barremian-aged Wessex Formation of the Isle of Wight, UK, offers a globally significant glimpse into the sauropod dinosaur faunas of the early Cretaceous. These deposits have yielded specimens of several neosauropod lineages, such as rebbachisaurids, titanosauriforms (including some of the earliest titanosaur remains), and possible flagellicaudatans. Here, we report an undescribed sauropod partial hindlimb from the Wessex Formation (NHMUK PV R16500) and analyse its phylogenetic affinities.
