Rockwood Posted February 9, 2013 Share Posted February 9, 2013 I recently read about a Middle Ordovician endoceratoid having a shell that reached a length of 9 to 10 m ! It would seem like something even close to that would make a spectacular museum exhibit but I don't recall ever seeing one. Have I missed something or is there perhaps a reason for the lack ?

painshill Posted February 9, 2013 Share Posted February 9, 2013 Yeah, I’ve seen them mentioned in various places too. For example Rhona Black mentions endoceratoids from the Lower Ordovician – Silurian up to 9 metres in “Elements of Palaeontology”. But I’ve never seen those references accompanied by pictures… or even a specific location where such specimens have been found and I've never seen anything like that size in a museum. I wonder if the size has been determined by extrapolation from fragmentary specimens… and if so, where?

Auspex Posted February 9, 2013 Share Posted February 9, 2013 From Wikipedia; Endocerida: "... Some long-shelled forms like Endoceras attained lengths as much as 3.5 metres (11 ft). The related Cameroceras is anecdotally reported to have reached lengths approaching 9 metres (30 ft), but these claims are not unproblematic (Teichert and Kümmel 1960). The overwhelming majority of endocerids and nautiloids in general are much smaller, usually less than a meter long fully grown..." From Wikipedia; Cameroceras: "...The partial shell of one giant Cameroceras yielded a total length estimated at the time at nearly 30 feet (9 m). This estimate has since been revised downward quite a bit; Frey (1995) gives a length of up to 6 m...

Rob Russell Posted February 10, 2013 Share Posted February 10, 2013 Here's a piece of endoceras that I found this past fall. It's from the Gelena formation, which makes it Ord. in age. You don't see them much bigger than this. I'm sure this critter was several meters in length. Finding my way through life; one fossil at a time.

RichW9090 Posted February 10, 2013 Share Posted February 10, 2013 (edited) I think it is worth posting the picture of Dinochochlea. what a cool trace fossil. Reminds me of the Devil's Corkscrews from the Badlands... Edited February 10, 2013 by RichW9090 The plural of "anecdote" is not "evidence".

Rockwood Posted February 10, 2013 Author Share Posted February 10, 2013 Did anyone notice that the Dinochochlea is next to a storage rack and not a display case ? 'I tell ya Rich, the inverts. they get no respect.' Link to comment Share on other sites More sharing options...
