Tiny fossil fish rewrites freshwater evolution after 70 million-year hideaway
Hidden for 70 Million Years, a Tiny Fossil Fish Changes Our View of Freshwater Evolution A minuscule skeleton about 4 centimeters long from the Late Cretaceous period has just rewritten a chapter of evolutionary history. Discovered by a collaborative team from Western University, the Royal Tyrrell Museum of Palaeontology, and international partners, this tiny fossil…

Fossilized ear bones rewrite the history of freshwater fish
A new timeline for the origin of otophysan fish Scientists have long noted that two‑thirds of all freshwater fishes possess a sophisticated hearing system known as the Weberian apparatus, a set of middle-ear bones that lets these fish hear much higher frequencies than most ocean species. In a stunning revision of this history, UC Berkeley…

Fossilized Ear Bones Rewrite Freshwater Fish History
Weberian Ear Bones Rewrite Freshwater Fish Origins For millions of years, freshwater fish have wowed scientists with their remarkable hearing abilities. Central to this capability is the Weberian apparatus, a set of small, bone-based connectors that transfers sound from an air-bladder system to the inner ear. In two-thirds of today’s freshwater species, including ubiquitous catfish…
