The Jurassic vegetation of Antarctica remains poorly known and, while there have been several reports of large fossil trees from that time period across the continent, detailed anatomical studies of their wood are extremely scarce. Here we describe new silicified woods of Early Jurassic (probably Toarcian) age from Carapace Nunatak, South Victoria ...

A fossil of Oniscidea, Tylidae gen. et sp. indet. from Kachin amber (Cretaceous Cenomanian), Myanmar, is described here. The convex body, the cephalon with a triangular protrusion between the antennae, and pereonites 2–6 with epimera demarcated from tergites indicate that this specimen belongs to the family Tylidae, but since it is not an adult the...

Studying palaeotsunamis is important to the comprehensive understanding of these events and their role in the geological evolution of the coasts of oceans and seas. The present work aims at summarizing the published information on Triassic tsunamis to document their spatiotemporal distribution and the related knowledge gaps and biases. A bibliograp...

The North China Craton underwent extensive and widespread crustal reworking (or decratonization) during the Mesozoic. However, how the decratonization operated is not well understood. Zircon compositions are widely used by the scientific community to reconstruct crustal thicknesses. In this study, we sampled 13 magmatic rocks in the Jiaodong Penins...

Hydrology is one of the most influential elements of geodiversity, where geology and geomorphology stand as the main values of abiotic nature. Hydrological erosion created by river systems destructing rock formations (eluvial process) from streams’ sources and then transporting and redepositing (alluvial process) the rock debris into the main river...

The Late Jurassic elasmobranch Protospinax annectans is often regarded as a key species to our understanding of crown group elasmobranch interrelationships and the evolutionary history of this group. However, since its first description more than 100 years ago, its phylogenetic position within the Elasmobranchii (sharks and rays) has proven controv...

Recently, a 53 million year old pteridosperm species, Komlopteris cenozoicus, was discovered at the west coast of Tasmania near Strahan, post-dating the end-Cretaceous extinction by about 13 million years. The discovery of this 'ghost lineage' prompted new excavations at its type locality, which led to the recovery of 52 new leaf specimens of K. ce...

The isoetalean lineage has a rich fossil record that extends to the Devonian, but the age of the living clade is unclear. Recent results indicate that it is young, from the Cenozoic, whereas earlier work based on less data from a denser taxon sampling yielded Mesozoic median ages. We analyzed node ages in Isoetes using two genomic data sets (plasto...

The diversity of praeaulacid wasps in Kachin amber is relatively poorly documented. Here, a new genus and species of praeaulacid wasp are described and illustrated from the mid-Cretaceous Kachin amber as Archeogastrinus kachinensis gen. et sp. nov., and placed in the subfamily Praeaulacinae. This new genus is distinguishable from the other Praeaula...

Acoustic communication has played a key role in the evolution of a wide variety of vertebrates and insects. However, the reconstruction of ancient acoustic signals is challenging due to the extreme rarity of fossilized organs. Here, we report the earliest tympanal ears and sound-producing system (stridulatory apparatus) found in exceptionally prese...
