Fossil Melandryidae (Coleoptera: Tenebrionoidea) from Eocene Baltic amber of the Sambian peninsula: new genus, six new species, new records and key to described taxa. Six new extinct representatives of the family Melandryidae, namely Electroxylita chronographica gen. et sp. nov., Madelinia capillata sp. nov., Microscapha kugelanni sp. nov., Phloiotrya inmarinata sp. nov., Symphora pollocki sp. nov., and S. glaesonauta sp. nov. are described from inclusions in Eocene Baltic amber. Twenty-eight additional fossil specimens of melandryid beetles belonging to ten species are reported. A list of Melandryidae described from Baltic amber is compiled and an identification key is provided.

A new Cretaceous family illuminates the early evolutionary history of True Sawflies (Hymenoptera: Tenthredinoidea).. A new family, †Eotenthredinidae, including two new species, †Eotenthredo sinensis gen. et sp. nov. and †Eotenthredo magna sp. nov., is described, based on nine adult specimens from the Early Cretaceous Yixian Formation, ~125 Ma. As the oldest known crown tenthredinoids to date, †Eotenthredinidae exhibits a mosaic of plesiomorphic and derived traits, serving as a crucial transitional taxon linking stem and crown tenthredinoids. We conduct a morphology-based phylogenetic analysis of Tenthredinoidea incorporating the most extensive sampling of Mesozoic fossils to date. Our resul…

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous-Paleogene boundary in western North America.. Premise The Chicxulub asteroid impact at the Cretaceous-Paleogene (K-Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well-documented "fern spore spike." However, fern macrofossil records across the K-Pg boundary are less understood. Methods We analyzed 698 fern macrofossils from 19 Cretaceous and 83 Paleogene localities in the Raton (Colorado and New Mexico), Denver (Colorado), and Williston basins (North Dakota and Montana), g…

The earliest beetle with mouthparts specialized for feeding on nectar is a parasitoid of mid-Cretaceous Hymenoptera.. Background During the Mesozoic, there were many insects in several holometabolous orders (Neuroptera, Mecoptera and Diptera) with elongated mouthparts adapted for feeding on nectar. The evolutionary history of the megadiverse order Coleptera, which has a great diversity of mouthparts and feeding strategies, is well documented since early Permian with a significant peak in diversity in the Triassic. Currently, however, there is no evidence that in the Mesozoic these beetles fed on nectar despite the recorded specializations for pollination of flowering plants in several famil…

Revisiting the enigmatic Cheirolepidiaceae: origins, phylogenetic relationships, and a new whole-plant concept.. Background and aims The extinct conifer family Cheirolepidiaceae spanned from the Late Triassic to early Palaeocene and was distributed worldwide. While it is known from multiple organs, there are no Cheirolepidiaceae whole-plant reconstructions to date. The relationships of Cheirolepidiaceae with different plant groups have been extensively discussed in the literature, but their phylogenetic position has not been thoroughly explored. To fill these gaps, we studied seed cones associated with other Cheirolepidiaceae organ remains from the Early Cretaceous of Arkansas and investiga…

This is a list of the fauna of the Mazon Creek fossil beds, a Carboniferous lagerstätte located in Grundy County, Illinois. The site is famous for its exceptional preservation of soft bodied fossils inside of ironstone concretions, and was one of the first fossil sites discovered to preserve soft bodied fossils. The Mazon Creek fossil beds are around 309-307 million years old, being approximately Moscovian in age. During the Carboniferous, this area was a lush, tropical delta system, about 10° north latitude of the equator. This ecosystem was formed by at least one river system that flowed in from the northeastern united states and met the ocean to form an Estuarine environment. This large…

Meganeura (Ancient Greek: μέγα (large) + νευρόν (vein or nerve)) is a genus of extinct insects from the Late Carboniferous (about 300 million years ago). It is a member of the extinct order Meganisoptera (also known as griffenflies), which resemble dragonflies and damselflies (with dragonflies, damselflies, and meganisopterans being part of the broader group Odonatoptera). While various species of Meganeura have been named, only one is now considered valid, the type species, M. monyi. Fossils of Meganeura were first discovered in Late Carboniferous (Stephanian) Coal Measures of Commentry, France, in 1880. In 1884, French paleontologist Charles Brongniart described the type specimen and assi…
