Conservation Science and Practice, Volume 7, Issue 4, April 2025.Abstract The “rhinorays” (giant guitarfish‐Glaucostegidae and wedgefish‐Rhinidae) are a critically endangered group of “shark‐like rays,” which have experienced steep global population declines in the past decade due to overfishing. Their slow life histories and high market value increase the risk of trade‐driven extinction and lead to trade‐offs ...

Eocene Shark Teeth From Peninsular Antarctica: Windows to Habitat Use and Paleoceanography
Paleoceanography and Paleoclimatology, Volume 39, Issue 11, November 2024.Abstract Eocene climate cooling, driven by the falling pCO2 and tectonic changes in the Southern Ocean, impacted marine ecosystems. Sharks in high‐latitude oceans, sensitive to these changes, offer insights into both environmental shifts and biological responses, yet few paleoecological studies exist.
