Wrangellian Posted December 29, 2011 Share Posted December 29, 2011 Some recent acquisitions that I think are 'pretty cool' ... If you know any of my data to be incorrect, please let me know. Graptolite: Cyrtograptus murchisoni Silurian, Wenlockian ~425my Builth Wells, Wales details: Link to comment Share on other sites More sharing options...
Wrangellian Posted December 29, 2011 Author Share Posted December 29, 2011 Conulariid: Conularia quichua Ulrich 1890 Lower Dev. Sicasica Fm, Patacamaya, ~100km S of La Paz, Bolivia Though it didn't break cleanly, I like this one because it's intact almost all the way down to the tip. Receptaculitid (Sponge? Chlorophyte alga?): Receptaculites occidentalis Salter Ordo.: Upper Sandbian? = Mowhawkian: ?Upper Turinian Black River Group Mascot, Knox Co., TN (I see lots of people put more than 2MB-worth of pics in a single post - how do they do that??)

Missourian Posted December 29, 2011 Share Posted December 29, 2011 Nice pieces. The receptaculitids are always fascinating. They are chlorophyte algae, dasyclads to be exact. Context is critical. Link to comment Share on other sites More sharing options...
Wrangellian Posted December 29, 2011 Author Share Posted December 29, 2011 OK, if you're confident of that I'll mark it as such. I have another alga, Coleochaete Parka decipiens that I will post also, as soon as I get it off the camera. Link to comment Share on other sites More sharing options...
Lloyd Posted December 29, 2011 Share Posted December 29, 2011 Nice specimens. Even if it didn't break cleanly, I really like that Conulariid. Link to comment Share on other sites More sharing options...
Ludwigia Posted December 30, 2011 Share Posted December 30, 2011 Sorry I can't give an opinion on your IDs but they are very nice specimens. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Wrangellian Posted January 1, 2012 Author Share Posted January 1, 2012 Thanks Ludwigia, I'm happy with the IDs unless someone happens to know there is something to correct or add. Here is the other one I meant to include: Early 'land plant' (freshwater green algae): Parka decipiens, Lower Dev. Old Red Sandstone, Carmyllie Series (=Group?), Forfar, Angus, Scotland. This was billed as the only known fossil representative of the Coleochaetales - probably related to earliest land plants. U. Sil. to L. Dev. range.

Wrangellian Posted January 1, 2012 Author Share Posted January 1, 2012 Thanks Carmine, It's not as nice as some of the other ones I see doing a Google Image search! But maybe those are exceptional examples - at least Ive got a specimen, incomplete tho it may be. Just doing a quick search there is a little about them here: http://steurh.home.xs4all.nl/eng/parka.html Link to comment Share on other sites More sharing options...

This was billed as the only known fossil representative of the Coleochaetales - probably related to earliest land plants. U. Sil. to L. Dev. range. I love it. It has an almost 'alien' appearance like some of the ediacaran creatures. Algae can be neglected as they are kind of stuck between 'plants' and 'invertebrates', yet they can also be spectacular.

Wrangellian Posted January 3, 2012 Author Share Posted January 3, 2012 I agree, they may not capture people's imagination like a dinosaur or shark but they are one of the Earth's denizens and one of the oldest, so they are just as interesting to me and I'll collect them wherever I can get them. I should post a pic of my Mary Ellen Mine stromatolite, it is beautiful and often used for lapidary but a good example of Earth's earliest forms of life (or the traces left by it, if you will)....
