Bone damage in Allopleuron hofmanni (Cheloniidae, Late Cretaceous)

Netherlands Journal of Geosciences - Geologie en Mijnbouw, 2013
AbstractWe describe pathologies and post-mortem damage observed in specimens of the late Maastrichtian marine cheloniid turtle Allopleuron hofmanni. Shallow circular lesions on carapace bones are common and possibly illustrate barnacle attachment/embedment. Deep, pit-like marks are confined to the neural rim and the inner surface of peripheral elements;

Marine debris ingestion by sea turtles (Testudines) on the Brazilian coast: an underestimated threat? [PDF]

, 2015
Assessment of marine debris ingestion by sea turtles is important, especially to ensure their survival. From January to December 2011, 23 specimens of five species of sea turtleswere found dead or dying after being rehabilitated ...

Loggerhead turtle, Caretta caretta (Linnaeus, 1758) (Testudines, Cheloniidae), as a new host of Monticellius indicum Mehra, 1939 (Digenea: Spirorchiidae) and associated lesiond to spirorchiid eggs

Helminthologia, 2017
The present note describes the occurrence of Monticellius indicum Mehra, 1939 (Digenea: Spirorchiidae) in an adult loggerhead turtle, Caretta caretta (Linnaeus, 1758), found on the coast of the state of Rio de Janeiro, Brazil. Pathological changes due to

DISTRIBUIÇÃO GEOGRÁFICA DE CHELONIA MYDAS (TESTUDINES: CHELONIIDAE)

Anais do I Congresso On-line Brasileiro de Biologia Marinha e Oceanografia, 2021
Introdução: As tartarugas verdes (Chelonia mydas) são classificadas como vulneráveis pelos critérios da IUCN. Os principais fatores relacionados ao seu declínio populacional incluem ações antrópicas como a captura incidental em redes de pesca, poluição das praias e oceanos, urbanização do litoral e aquecimento global.

A new species of Peritresius Leidy, 1856 (Testudines: Pan-Cheloniidae) from the Late Cretaceous (Campanian) of Alabama, USA, and the occurrence of the genus within the Mississippi Embayment of North America.

PLoS ONE, 2018
Late Cretaceous members of Peritresius belong to a diverse clade of marine adapted turtles currently thought to be some of the earliest representatives of the lineage leading to modern hard-shelled sea turtles (Pan-Cheloniidae).

Turtle remains from the late Miocene of the Cessaniti area, southern Italy—insights for a probable Tortonian chelonian dispersal from Europe to Africa

Swiss Journal of Palaeontology, 2020
We here describe turtle remains from the late Miocene (Tortonian) of Cessaniti (Calabria, southern Italy), an area that recently has been palaeogeographically reconstructed as being, at that time of the Neogene, directly connected (or at least rather ...

Nest-to-Surf Mortality of Loggerhead Sea Turtle (Caretta caretta) Hatchlings on Florida’s East Coast

Frontiers in Marine Science, 2019
Sea turtles are vulnerable immediately after emerging from nests and before they reach the surf. Mortality rates during this brief period are largely unknown. Many sea turtle monitoring programs measure hatchling production from nest inventories.

Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, Volume 33, Issue 3, Page 463-478, June 2026.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...
