New fossils of Sirenia from the Middle Eocene of Navarre (Western Pyrenees) : the oldest West European sea cow record [PDF]

, 2010
Postcranial remains of Sirenia from the early Middle Eocene (late Lutetian) Urbasa-Andia Formation of Navarre (Western Pyrenees) are described. The material consists of two partial atlas vertebrae, one humerus and several dorsal ribs (from Arrasate ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, Volume 309, Issue 8, Page 2124-2150, August 2026.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Effects of Simulated Herbivory on the Thermal Resilience of Two Temperate Seagrass Species

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study investigates how reduced leaf size via simulated herbivory influences the thermal performance of temperate seagrasses. Simulated herbivory enhanced physiological performance and resilience under elevated temperatures in Posidonia australis, but not in Heterozostera tasmanica.

Metaxytherium subapenninum (Bruno, 1839) (Mammalia, Dugongidae) the latest sirenian of Mediterranean basin. Journal of Vertebrate Paleontolology

, 2012
Metaxytherium subapenninum was a halitheriine dugongid distributed along the northwestern coasts of the Mediterranean Basin during the early and late Pliocene. It represents the latest sirenian species of the Mediterranean Basin, the latest Metaxytherium

Progesterone monitoring and gestation length in Amazonian manatees (Trichechus inunguis)

Theriogenology Wild
Knowledge of pregnancy length and the physiological parameters during pregnancy is an important tool for pregnancy diagnosis in free-ranging and captive individuals and for the correct husbandry of captive pregnant females. Therefore, this study aimed to

Miocene Shark and Batoid Fauna from Nosy Makamby (Mahajanga Basin, Northwestern Madagascar).

PLoS ONE, 2015
Madagascar is well known for producing exceptional fossils. However, the record for selachians remains relatively poorly known. Paleontological reconnaissance on the island of Nosy Makamby, off northwest Madagascar, has produced a previously undescribed ...

Metagenomic Insights Into Red Sea Biodiversity Across the Web of Life

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Deep‐sequencing shotgun metagenomics of Red Sea benthic sediments reveals biodiversity across the web of life, from viruses to animals. Despite the strong dominance of prokaryotic DNA, low‐abundance eukaryotic reads capture broad taxonomic diversity. Open‐ocean communities are primarily structured by depth, whereas coastal eukaryotic communities follow

Neurocranial bones are key to untangling the sea cow evolutionary tree: osteology of the skull of Sobrarbesiren cardieli (Mammalia: Pan-Sirenia) [PDF]

, 2022
The pan-sirenian Bauplan is conservative, probably owing to the constraints of adaptation to an aquatic lifestyle. Gathering morphological data from extinct forms is complex, resulting in poorly resolved phylogenies for stem pan-sirenians.

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...
