On The fossil guy website on Cow Sharks, there is a tiny detail that intrigued me.
“There are also some differences between male and female teeth. These differences, however, will not be discussed here.”
Well then we better discuss them here! Anybody know what these are? For me the bluntnose sevengill would be more relevant, but for the sake of learning add sex differences in the teeth of any and all Cow shark species. Thanks all!
