Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

TAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

Evolution of the East Antarctic Ice Sheet Since Glacial Inception From Seismic Stratigraphic Records in Vincennes Bay

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Seismic reflection data from Vincennes Bay, East Antarctica, provide the first insights into the Cenozoic evolution of the East Antarctic Ice Sheet (EAIS) in the Knox Coast. Long‐distance seismic horizon correlation allows age estimates for the seismic stratigraphic framework constructed for the continental shelf.

Occurrence and evolution of cannibal behaviour in extant snakes

Biological Reviews, Volume 101, Issue 2, Page 644-664, April 2026.
ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

Cladistics, Volume 42, Issue 2, Page 159-171, April 2026.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures

Journal of Metamorphic Geology, Volume 44, Issue 3, Page 226-245, April 2026.
ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Early Cretaceous environments

Journal of the Geological Society, 1993
A one day meeting of the British Sedimentological Research Group (BSRG), convened by K. G. Taylor and A. H. Ruffell, was held at the Postgraduate Research Institute for Sedimentology, University of Reading on 23 June 1992. The meeting set out to consider what is known about palaeoenvironments of the NW European early Cretaceous and to ...

An Early Cretaceous labyrinthodont

Alcheringa: An Australasian Journal of Palaeontology, 1991
A crescentic intercentrum and isolated skull bone have been recovered from Early Cretaceous rift valley sediments of the Gippsland Basin, southeastern Victoria. The intercentrum, which is unquestionably from a temnospondyl labyrinthodont, and an ornamented cranial bone confirm the earlier identification of a mandible from a nearby locality as ...

Mammalian hairs in Early Cretaceous amber

Naturwissenschaften, 2010
Two mammalian hairs have been found in association with an empty puparium in a approximately 100-million-year-old amber (Early Cretaceous) from France. Although hair is known to be an ancestral, ubiquitous feature in the crown Mammalia, the structure of Mesozoic hair has never been described.

Early Cretaceous Dinosaurs from the Sahara

Science, 1994
A major question in Mesozoic biogeography is how the land-based dinosaurian radiation responded to fragmentation of Pangaea. A rich fossil record has been uncovered on northern continents that spans the Cretaceous, when continental isolation reached its peak. In contrast, dinosaur remains on southern continents are scarce.
