Cam28 Posted December 31, 2018 Share Posted December 31, 2018 Was just reviewing a paper that covers this, which apparently can be used to calculate mackerel shark total body lengths based on an anterior tooth to some accuracy. [Length in cm = -26.665 + crown heights (in mm) times 12.499] Since this formula was devised from modern goblin sharks, anyone know if it can also be used with carcharhiniform/ground shark teeth or are they too dissimilar? (Have a somewhat large hemipristis upper anterior I've meant to try this on) Link to comment Share on other sites More sharing options...

You could look around the web for someone selling modern Hemipristis (H. elongatus) jaws. A good label will have the total body length of the shark so you can calculate from the upper anteriors of that one. You could also try contacting Dr. Gordon Hubbell. 1 Link to comment Share on other sites More sharing options...
