A comparison between the growth of the ‘teeth’ of the paraconodont Furnishina (bottom) and the euconodont Proconodontus (top). They have been subdivided into a number of discrete growth stages, revealing a common mode of growth between these groups. Euconodonts evolved from paraconodonts through the origin of an enamel-like crown (red, transparent). Credit: Image by DJE Murdock
