Oldest bony fish fossils reveal story of early vertebrates
A tiny fossil fish, roughly 3 centimeters long and approximately 436 million years old, has been identified as the oldest known bony fish ever found, pushing back the timeline for when the ancestors ...

One of just two vertebrates without a jaw, sea lampreys that are wreaking havoc in Midwestern fisheries are simultaneously helping scientists understand the origins of two important stem cells that ...
During the course of evolution, the mammalian cranio-mandibular secondary joint—formed by the dentary condyle and the squamosal glenoid fossa, which replaced the reptilian articular–quadrate ...
Early jawless fish were likely to have used bony projections surrounding their mouths to modify the mouth's shape while they collected food. Experts have used CT scanning techniques to build up the ...
