Ryohei Posted June 14, 2009 Share Posted June 14, 2009 Hi I'm hoping somone can help with the identification of some of these items. The first two items were gifts purchased by my daughter in a gift shop somewhere in the North of Scotland. The polished ovoid was labelled as a "Nautiloid" (1 view), and the other as an "Ammonite" (2 views). I think I might just about have guessed the latter, but I have no idea what species it might be. Also, I have no clue as to the geographical origin of these items. In the case of the third item (2 views given) I can tell you that this came out of shale from the Bishop Hill Quarry in Scotland that I have mentioned in another thread - it is rock from the Lower Carboniferous Group which comes into the Visean stage(= Mid-Mississippian I think). To me it looks like some kind of immature mollusc. Sorry the pics aren't too wonderful but it was the best I could do. Any comments, suggestions etc as to the identification and dating of these items would be most welcome. Thanks Alan p.s. Can anyone recommend either a website or a book (preferably UK-based) that can help with the identification of such items?

Auspex Posted June 14, 2009 Share Posted June 14, 2009 As I am capable of picking only the low-hanging fruit, allow me to suggest that the polished specimen came from Morocco. It is an orthoconic cephalopod.

Ryohei Posted June 14, 2009 Author Share Posted June 14, 2009 Funny you should say that, Auspex. wass thought it was an Orthoceras from Morocco, too. I guess I'll buy that.

tracer Posted June 14, 2009 Share Posted June 14, 2009 As I am capable of picking only the low-hanging fruit, allow me to suggest that the polished specimen came from Morocco. It is an orthoconic cephalopod. yeah, yeah, he's right, he's right, and if it was a lazy one and you had its picture as your avatar, it'd be an iconic laconic orthoconic cephalopod. (and before you start sayin' how bad that was, bear in mind that i was trying to figure out how to use "ionic" and "hydroponic" in there but punted.)

Dicranurus Posted June 14, 2009 Share Posted June 14, 2009 I think that ammonite is from Madagascar and it is jurassic and its genus is probably Perisphinctes or Orthosphinctes?

mdpaulhus Posted June 14, 2009 Share Posted June 14, 2009 I agree with the above post on the ammonite. This is a Perisphinctes from the Upper Jurrasic of Madagascar. Link to comment Share on other sites More sharing options...
Shamalama Posted June 14, 2009 Share Posted June 14, 2009 Just a wild stab in the dark on the third piece.... Horn Coral? Looks a little like some that I've seen in Devonian strata, but I know you said it came from the Carboniferous. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

ayahuang Posted June 15, 2009 Share Posted June 15, 2009 I think that ammonite is from Madagascar and it is jurassic and its genus is probably Perisphinctes or Orthosphinctes? i think so about the Ammonite, but not too old.. Link to comment Share on other sites More sharing options...
Ryohei Posted June 15, 2009 Author Share Posted June 15, 2009 @ Shamalama: It's definitely Early-ish carboniferous. When I get a bit more time I'll retry the pic and see if I can make it any better. Trouble is, the specimen is so dang tiny............... "It is better to remain silent and be thought a fool, than to speak out and remove all doubt."
