... well it got me thinking ... comparing the squidcam versions. Has anyone a photo of a Nautilus egg that they could post online? Has anyone described/reported anything like this in the fossil record? Surely if cephalopod soft parts can (albeit rarely) fossilize, surely an egg with an outer, hardened egg capsule could fossilize also.
Anyone want to hazard a guess whether ammonites and nautiloids deposited few large eggs to the seabed, brooded their young, or did as most squid do, that is release eggs freely into the water column, singly or in large gelatinous structures, or attach them to the seabed, singly or in gelatinous strings.
Remains of cirrate (finned octopods) eggs litter the deep sea in places around New Zealand, depths > 2500m, as do squid beaks.
