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.
"The impact of the PETM event on life at the time is of wide interest. But a major gap in our understanding is how life in the tropics responded, because this region is not well-sampled for many fossil groups," said U-M paleontologist Matt Friedman, co-author of a study published online May 17 in the journal Geology.
