Fossils reveal some fish survived in ancient hot water

Fossils of fish from a period of ancient climate change show that some species survived and even thrived during the time. ....

Egyptian fossil surprise: Fishes thrived in tropics in ancient warm period, despite high ocean tempe

Photos and Map
The Paleocene-Eocene Thermal Maximum, or PETM, was a short interval of highly elevated global temperatures 56 million years ago that is frequently described as the best ancient analog for present-day climate warming.
Fish are among the organisms thought to be most sensitive to warming climates, and tropical sea-surface temperatures during the PETM likely approached temperatures that are lethal to some modern marine fish species, according to some estimates.
But newly discovered fish fossils from an eastern Egyptian desert site show that marine fishes thrived in at least some tropical areas during the PETM. The study, from a team of Egyptian scientists and a University of Michigan colleague, provides a snapshot of an ecosystem during an extreme warming event and may provide insights for the future. ....

Egyptian fossil surprise: Fishes thrived in tropics in ancient warm period, despite high ocean temperatures

The moonfish Mene, which is still alive today in the Indian and Pacific oceans, is a common fossil at Ras Gharib A. Scalebar equals 10 mm. From El-Sayed et al. in Geology, 2021.
