Show Us Your Cordaites

Recommended Posts

Missourian

Has anyone here collected these Pennsylvanian plants? If so, show 'em. :)

 

This gymnosperm tree is classified under a handful of genera:

 

Cordaites - leaves

Cordaianthus - seed cone

Cardiocarpus - seed

Artisia - stem

Amyelon - roots

 

I'll start with a few I've posted on the forum already....

 

Leaf bundle (Cordaites):

Leaf (Cordaites):

Stump and roots:

 

96-Winterset-Cordaites-stump.jpg

 

Roots (Amyelon?):

Roots (Amyelon?):

All are from the Pennsylvanian Winterset Limestone of the Kansas City area.

Thanks for sharing these. I have a few found in the mazon creek area - most I find are single leaf variety.

Hi Missourian

thank you for your comment, leaves bundles are very difficult to find on both sides ofcontinents, I also like the contrast and color "honey" of your specimens.... :wub:

Best regards

Hello all.

Missurian, nice topic and wonderful finds and pics!!!.

Bruno, excellent cordaites collection!!!

Nice the rest contributions, as well!

I came into this topic yesterday and in my surprice, I realized that the unkown to me plant material I have found last Sunday in my hunting area (late miocene middle Crete island, Greece) bears some similarities to the stuff presented here. I searced my available papers on the Cretan flora fossils, but I didn't find anything relative.

What's your opinion?

I attach pics of my slab and of Missurian's leaf and seed.

I don't think the cordaitales made it past the Triassic. Your specimen, though, may have filled a similar ecological niche.

Hey Ya'll! I saw this thread and maybe late to the game. While going through boxes of my collection last evening I came across some specimens that I've been told that are Cordaite casts from the Alabama / Pottsville formation. Some of these are Cordaites and others may not be, so please point that out. Some of these specimens are posted in my gallery.

Here are some more roots found during a trip last weekend through eastern Clay County, Missouri....

 

Winterset Limestone:

Westerville Limestone:

post-6808-0-26580000-1345541304_thumb.jpg

 

It turns out these root molds can be found in many different limestone units in the area. Only the Winterset preserves the leaves and stems in the beds above the roots.
