Jones1rocks Posted August 12, 2017 Share Posted August 12, 2017 I feel fairly certain that this Mazon fossil is of a Cyclopteris leaf, but I'm wondering if individual leaves of this size are common in finds? The leaf measures 2 x 2" and is lightly pyritized. Link to comment Share on other sites More sharing options...

Plantguy Posted August 13, 2017 Share Posted August 13, 2017 Very Nice specimen. I've seen a number of them but havent collected there and cant comment on commonality. I defer to some of the local Mazon Creek collectors and maybe they can comment further but Jack Wittry's book pg 45 The Mazon Creek Fossil Flora does mention that Cyclopteris trichomanoides which he has pictures within as being uncommon and it is the most often found Cyclopterid in the Mazon Creek flora. Not sure if thats what you have. Thanks for showing us! Regards, Chris 1 Link to comment Share on other sites More sharing options...

Rob Russell Posted August 13, 2017 Share Posted August 13, 2017 Jack Wittry describes cyclopteris trichomanoids as being uncommon. I've only collected two specimens myself. Compared to literally hundreds of pecopteris fossils, for example. 1 Finding my way through life; one fossil at a time. Link to comment Share on other sites More sharing options...
