A 289-million-year-old Captorhinus aguti fossil from Oklahoma preserves three-dimensional skin and tissues, including proteins, revealing rib-based (costal) breathing and the oldest known protein remnants in fossils, offering new insight into early amniote evolution.
In a multi-year exploration of more than 60 limestone caves in Battambang, Cambodia, researchers uncovered rare and new species including a flying snake and a vivid, heat-sensing pit viper, along with camouflaged leaf-toed geckos and bright millipedes, highlighting how isolated karst ecosystems foster unique life and underscoring the need to protect these habitats, of which only about 1% is legally safeguarded.
A survey of Cambodia’s karst limestone caves uncovered 11 species new to science, including a turquoise pit viper with a heat-detecting head organ, the ornate flying snake, several geckos (one named Gekko shiva), and other invertebrates, found across 64 caves on 10 karst hills between 2023 and 2025. Researchers warn that these isolated cave ecosystems are under threat from limestone quarrying, habitat loss, and overtourism, and call for protective status and continued conservation work.
Paleontologists have found the oldest known fossilized reptile skin, dating to about 289 million years ago in Oklahoma’s Richards Spur cave. The tiny skin fragment, preserved by oil-based substances and low-oxygen conditions, shows crocodile-like scales and suggests early reptiles had water-conserving skin long before dinosaurs; researchers think it likely belonged to Captorhinus aguti, with future work aiming to link the skin to a full skeleton to better understand early amniote life on land.
Paleontologists report the earliest fossil imprint of reptile skin with belly scales and a cloacal vent dating to about 290 million years ago, pushing back the origin of the cloaca in amniotes and beating the previous 120-million-year record.
Scientists describe a 298–299 million-year-old fossil imprint from a bolosaurian reptile in Germany, preserving belly scales and a cloaca—the oldest known soft-tissue imprint of its kind and the earliest reptile skin details—offering new insights into early reptile evolution. Named Cabarzichnus pulchrus, the 3.5-inch trace extends the fossil record of back-end anatomy by more than 150 million years and suggests anatomical similarities to modern turtles, lizards, and snakes.
Researchers report 280-million-year-old mesosaur embryos from Brazil and Uruguay, providing the oldest direct evidence that these ancient aquatic reptiles could give birth to live young, pushing the origin of viviparity back about 60 million years; findings also indicate potential parental care, with some fossils suggesting a mixed strategy where at least one egg was found at an advanced stage of development.
Researchers discovered that many reptiles excrete solid uric acid crystals as a water-saving adaptation, which could inspire new treatments for human conditions like gout and kidney stones caused by uric acid buildup.
The discovery of the 242-million-year-old lepidosaur fossil Agriodontosaurus helsbypetrae in the UK challenges previous beliefs about early reptile evolution, revealing unexpected traits and suggesting a more complex evolutionary history for lizards, snakes, and the tuatara.
A study from the University of Lincoln shows that red-footed tortoises can experience long-term mood states similar to mammals and birds, challenging traditional views on reptile sentience and impacting animal welfare practices.
The article describes the presence of non-venomous fox snakes in the Upper Peninsula, highlighting a recent mating encounter observed by the author, and emphasizes the ecological benefits of snakes as natural rodent control, along with a reminder to be cautious of turtles during egg-laying season.
Indian authorities arrested a man at Mumbai airport for attempting to smuggle dozens of rare and venomous reptiles, including 47 vipers, concealed in his luggage, highlighting ongoing wildlife smuggling issues in India.
Recent research reveals that pythons, traditionally considered solitary creatures, actually exhibit complex social behaviors. These findings challenge previous assumptions about reptilian social structures and suggest that pythons may form social bonds and interact with each other more than previously thought.
A new species of gracilisuchid reptile, Parvosuchus aurelioi, has been discovered in the Santa Maria Formation in Brazil. This small, crocodile-like reptile lived around 237 million years ago during the Triassic period and is the first gracilisuchid confirmed in Brazil. The discovery, which includes a complete skull and partial skeleton, highlights the diversity of pseudosuchians before the dominance of dinosaurs.
The Public Health Agency of Canada has identified geckos as the likely source of a salmonella outbreak affecting seven provinces, with 35 confirmed cases and five hospitalizations. Individuals who became ill had direct or indirect contact with geckos or their environments, and some cases involved children aged five and under. The agency emphasizes the importance of reptile owners and business operators in preventing illnesses linked to these pets, as symptoms of salmonella poisoning can include fever, chills, nausea, vomiting, diarrhea, headache, and abdominal cramps.
