Top Trilo Posted November 23, 2020 Share Posted November 23, 2020 I was trying to find the longest straight shelled cephalopod length but was unsuccessful, I heard anywhere from 7-14 feet. What's the real answer?

Tidgy's Dad Posted November 23, 2020 Share Posted November 23, 2020 The Endoceratidae contain the longest fossil cephalopod shells known. Shells of up to 3 metres are known, but it is difficult to estimate the full length of the animal including its soft parts. 5.7 metres (18.7 feet) is a reasonable estimate. Dubious estimates of Cameroceras include reports of it being up to 11 metres (35 feet) long. 4 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
