The first macrofossil record of parasitic plant flowers from an Eocene Baltic amber
HeliyonParasitic plants left little trace in the macrofossil record, making their evolutionary history mysterious. Baltic amber and other fossil lagerstätts have provided plenty of angiosperm fossils, there are only three reports of fossil leaves (cf. Schoepfia

PLoS ONEThe fossil record of parasitism is poorly understood, due largely to the scarcity of strong fossil evidence of parasites. Understanding the preservation potential for fossil parasitic evidence is critical to contextualizing the fossil record of ...

Separation and Valorization of Chlorine From Tail Gas Streams
Angewandte Chemie International Edition, EarlyView.A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

BIOEROSION OF THE PLIO-PLEISTOCENE TRANSGRESSION OF SOUTHERN ITALY
Rivista Italiana di Paleontologia e Stratigrafia, 2020 During the Pliocene and Lower Pleistocene, the structural unit of the Murge was largely submerged by a marine transgression. As the sea advanced, the limestone basement surface was invaded by bioeroding organisms whose borings are well preserved through ...

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Autobiographical Trace Fossils
, 2012 Ephemeral islands, petrified raindrops, volcanic dust from Pompeii, a shared birthday with a volcano. Certain geological processes have a way of evoking a more personal response to the idea of geological time. What does a time span of 300,000,000 years actually mean?

The Anatomical Record, EarlyView.Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.
