Herb Posted September 24, 2013 Share Posted September 24, 2013 This is a Crania sp. inarticulate brachiopod attached to a Eucalyptocrinites sp. calyx from the Silurian Waldron Shale from central Indiana. The calyx is 2 1/4" (5 cm) across. The brachiopod is about 3/4" across.(2cm). The blue circled item is a single element bryozoan, like the ones found in the lower Devonian Birdsong formation of central Tennessee. 2 "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.

Shamalama Posted September 25, 2013 Share Posted September 25, 2013 That elemental bryozoan looks like mostly Calcium to me. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Herb Posted September 25, 2013 Author Share Posted September 25, 2013 (edited) That elemental bryozoan looks like mostly Calcium to me. If you look at the original it looks like a miniature volcano, you can see the zooid. I will take a better picture of one.

Herb Posted September 25, 2013 Author Share Posted September 25, 2013 Here is one from the L.Devonian Birdsong Form.

Shamalama Posted September 28, 2013 Share Posted September 28, 2013 Looks very similar to a crinoid holdfast too. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Herb Posted September 29, 2013 Author Share Posted September 29, 2013 It does but it is Ptylodictya tenuis. It's only 3-4mm wide.

Shamalama Posted October 1, 2013 Share Posted October 1, 2013 Thanks Auspex. I have that document but I was hoping for a descriptive paper or something. So far I've only seen fossils of that species illustrated from Tennessee (in the guide that you linked to) but no where else. I can't find an entry for it on Paleodb.org either. 1 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Herb Posted October 1, 2013 Author Share Posted October 1, 2013 (edited) another from the Birdsong form. They are common in this formation.

Firstly, Ptylodictya doesn't exist anymore. It was replaced by Ptilodictya over a hundred years ago. Bryozoa.net, Mindat and Paleodb.org make no mention of either Ptylodictya or Ptilodictya tenuis. I can't find a proper paper either. Looks more like a crinoid holdfast to me, some specimens of which are surrounded by encrusting bryozoa. Edited September 12, 2022 by Tidgy's Dad 2 Life's Good!
