fossil soft body parts and belemnites and related

[Hajar]

I don't know about octopods, but this seems to mean that my Phragmoteuthis is a girl.

 

[DWhatley]

so the enlarged pair of mega-onychites is found on females (not clear which sex has them in your quote)?

 

[Hajar]

True! They didn't specify, but I'd been looking at rom the Löwentor-Museum in Stuttgart, posted by Sordes together with his accompanying information. The mega-onychites are inferred to have belonged to the males. My Phragmoteuthis doesn't show them.

 

[Architeuthoceras]

Does your Phragmoteuthis have a guard?

 

[DWhatley]

Thanks for the clarification and putting me back on the same page by explaining that your determination of female was the absence of the enlargements. It would be curious if the enlarged suckers on some males octopuses have no purpose today and are just throw backs but there must have been some reason for the dimorphistic trait.

Thanks djbirdnerd. We have this on the beaks thread. Fig.7 is excellent.
