The end of the ‘living fossil’ tale? A new look at Triassic specimens assigned to the tadpole shrimp Triops cancriformis (Notostraca) and associated phyllopods from the Vosges region (eastern France)

open access: yesPapers in Palaeontology, Volume 10, Issue 5, September/October 2024.
Abstract Notostracan branchiopods reported from the Lower Triassic Voltzia Sandstone Lagerstätte in northeastern France have previously been assigned to Triops cancriformis, making this species the longest persisting animal in earth history. Careful restudy of the splendidly preserved material indicates that the species can be well characterized but ...

Diet of Mesozoic toothed birds (Longipterygidae) inferred from quantitative analysis of extant avian diet proxies [PDF]

open access: yes, 2022
BackgroundBirds are key indicator species in extant ecosystems, and thus we would expect extinct birds to provide insights into the nature of ancient ecosystems. However, many aspects of extinct bird ecology, particularly their diet, remain obscure.

Inter-amphibian predation in the Early Cretaceous of China [PDF]

open access: yes, 2019
For most fossil taxa, dietary inference relies primarily on indirect evidence from jaw morphology and the dentition. In rare cases, however, preserved gut contents provide direct evidence of feeding strategy and species interaction.

Variations of sedimentary environment under cyclical aridification and impacts on eodiagenesis of tight sandstones from the late Middle Jurassic Shaximiao Formation in Central Sichuan Basin [PDF]

open access: yes
Understanding eodiagenesis is essential to decoding the diagenetic pathways of tight sandstones that act as excellent unconventional oil & gas reservoirs.

A Jurassic acanthocephalan illuminates the origin of thorny-headed worms [PDF]

open access: yes
Acanthocephala (thorny-headed worms), characterized by the presence of an eversible proboscis with hooks, are a diverse endoparasitic group that infect a wide range of vertebrates and invertebrates1. Although long regarded as a separate phylum, they have

Phylogenetic placement of Adalatherium hui (Mammalia, Gondwanatheria) from the Late Cretaceous of Madagascar : implications for allotherian relationships [PDF]

open access: yes, 2020
The phylogenetic position of Gondwanatheria within Mammaliaformes has historically been controversial. The well-preserved skeleton of Adalatherium hui from the Late Cretaceous of Madagascar offers a unique opportunity to address this issue, based on ...

Sea dragons of Avalon [PDF]

open access: yes, 2010
Tourists driving through the village2 of Street on their way to Glastonbury might well wonder at the representation of a skeleton on the road sign. Could this perhaps be a warning that this stretch of the A39 is a roadkill hotspot?

Frequência de preservação de biomateriais não mineralizados no registro fóssil de répteis mesozoicos: uma abordagem sobre pterossauros e répteis marinhos / Frequency of non-mineralized biomaterials preservation in the fossil record of Mesozoic reptiles: an approach on pterosaurs and marine reptiles [PDF]

open access: yes, 2021
Nas últimas décadas, vários estudos encontraram preservação excepcional de diferentes biomoléculas originais em dinossauros. Porém, grupos distintos de répteis que dominaram ares, mares e oceanos na Era Mesozoica, como pterossauros, ictiossauros ...
