Tiny-weenie-itsy-bitsy speck of a fossil.
Ive been looking for something Phil, no luck. Studies have been done on Nautilus, and judging from some of the repaired shells of other ammonoids on the ammonoid pathology thread, i would have to think that it didnt take very long for an ammonoid to grow a shell. The baby snails in my garden are full grown by the end of summer. I dont know if ammonoids would have lived as long as nautiloids, or grew shells as fast as snails, but I imagine they would be mature within a year and live for at least two years, some of the larger ones living longer (no proof or evidence, just speculation ) I'll keep looking.Phil said:have any conclusions been drawn as to how long goniaties may have lived based on examinations of these features?
