Were the cephalic spines of Xenacanthid sharks venomous
Petalodus12 posted a topic in General Fossil Discussion
Hi all, I have seen and heard from multiple different sources that the cephalic spines of Xenacanthid sharks are considered to have been venomous. This is usually supported by the serrated nature of these spines and a canal that runs down the middle of them. Has any research been done to prove or disprove this hypothesis. I know that we can never know for sure but I am curious if there is any scientific support to these claims. Thanks in advance, Zach- 17 replies
