shorty Posted February 17, 2009 Share Posted February 17, 2009 Hello! What do you think of this? Is it just a twig in the middle of a blob? Maybe a Cyclus Americanus? Mazon Creek concretion, pit 11, Kankakee County, IL Thanks so much! Kim Link to comment Share on other sites More sharing options...
Auspex Posted February 17, 2009 Share Posted February 17, 2009 I vote for a (very well defined) Cyclus; very nice!

Bill Posted February 17, 2009 Share Posted February 17, 2009 Thanks Jimmy. I thought it might be something like that but, googleing Cyclus brought up loads of hits for cycling and de-inked waste paper, etc. KOF, Bill.

Should I just label this one Cyclus? or do I need to figure out the species? (if that's even possible?) Link to comment Share on other sites More sharing options...
Auspex Posted February 17, 2009 Share Posted February 17, 2009 Should I just label this one Cyclus? or do I need to figure out the species? (if that's even possible?) As far as I know, your choices for Mazon Creek are either Cyclus americanus or Cyclus americanus.

There's a man on ebay who has three different species he's offering up for sale. Cyclus americanus, obesus & halicyne. Richardson's guide describes them - I'm not home or I'd look them up. halicyne is the rarest ??- I think it says it has a decorated shell. Anyway - Cyclus is good enough? -unless I want to start selling it for the big bucks on ebay? Link to comment Share on other sites More sharing options...
Auspex Posted February 17, 2009 Share Posted February 17, 2009 Are all three known from Mazon? Man, I'm way out of date.

crinus Posted February 18, 2009 Share Posted February 18, 2009 Actually there are only two species under the Cyclus, amercanus and obesus. The other cycloids have their own genus and are Halicyne max and Apionicon apioides. All are found at Mazon Creek localities. That makes four. Those of us that collected there years ago use to put these in the class Cycloidea and that is no longer valid. The class is Maxillopoda. All cyclus go onto the subclass Halicyna and the Order is Cycloidea. The reference for all of this is JP 71(2) 1997. Mazon Creek Cycloidea, Schram, Vonk and Hof.

In your opinion, is Cyclus americanus the correct label for this one? Link to comment Share on other sites More sharing options...
crinus Posted February 18, 2009 Share Posted February 18, 2009 Thanks for the info!!In your opinion, is Cyclus americanus the correct label for this one? I can't tell which one you have. Preservation is probably not the best. I would just label it as Cyclus sp. Link to comment Share on other sites More sharing options...
