The Thoracotremata is a large and successful group of "true" crabs (Decapoda, Brachyura, Eubrachyura) with a great diversity of lifestyles and well-known intertidal representatives. The group represents the largest brachyuran radiation into terrestrial and semi-terrestrial environments and comprises multiple lineages of obligate symbiotic species. In consequence, they exhibit very diverse physiological and morphological adaptations. Read More

The Paleocene-Eocene Thermal Maximum (PETM) is recognized globally by a negative excursion in stable carbon isotope ratios (δC) in sedimentary records, termed the carbon isotope excursion (CIE). Based on the CIE, the cause, duration, and mechanisms of recovery of the event have been assessed. Here, we focus on the role of increased organic carbon burial on continental margins as a key driver of CO drawdown and global exogenic δC during the recovery phase. Read More

Paleocene-Eocene hyperthermal events are a current research focus in the fields of sedimentology and paleoclimatology. The Fushun Basin in northeast China contains continuous continental Eocene fine-grained rocks, and a series of Eocene hyperthermal events in the Fushun Basin have been identified. Because of the high cost of high-precision isotope data testing, it is necessary to find new and alternative paleoclimate parameters. Read More

Snapping turtles (Pan-Chelydridae) play an important role in modern ecosystems throughout North America, but their fossil record is notably poor. We here describe a new species of fossil pan-chelydrid, Chelydropsis aubasi, from the Middle Eocene (MP15, Bartonian) of Chéry-Chartreuve, Department of Aisne, France, based on a series of fragments that document most of the shell. The new species not only bridges the morphological gap between earlier pan-chelydrids from North America and later pan-chelydrids from Europe but also advances the arrival of the group from North America to Europe by at least 10 million years.

The Paleocene-Eocene Thermal Maximum (PETM) is recognized by a major negative carbon isotope (δC) excursion (CIE) signifying an injection of isotopically light carbon into exogenic reservoirs, the mass, source, and tempo of which continue to be debated. Evidence of a transient precursor carbon release(s) has been identified in a few localities, although it remains equivocal whether there is a global signal. Here, we present foraminiferal δC records from a marine continental margin section, which reveal a 1. Read More
