Auspex Posted June 13, 2014 Share Posted June 13, 2014 Real nifty ammonite; big ol' knobs and intricate sutures!

PFOOLEY Posted September 22, 2014 Share Posted September 22, 2014 I have no clue..thoughts? Looks like broken up Toredo wood. Really strange looking gastropod...interesting features.... edit: love the operculum on this one... I think that may be a bivalve in a small concretion. Looks like you had quite a day Thanks for sharing! 1 "I am glad I shall never be young without wild country to be young in.

jpc Posted September 22, 2014 Share Posted September 22, 2014 I agree on the Teredo wood. I have seen occasional pieces in the Frontier Fm around here which, judging by your ammonites, is similar in age to your stuff. 1 Link to comment Share on other sites More sharing options...
Pilobolus Posted September 22, 2014 Author Share Posted September 22, 2014 Thanks gentlemen! So in essence, Teredo wood is (in my example) a infilling cast of wood burrow left from a marine worm, which then weathered out? Link to comment Share on other sites More sharing options...
Pilobolus Posted September 22, 2014 Author Share Posted September 22, 2014 Well, that advice was helpful in the identification of another sample I had not yet photographed. This was extremely friable material, so I was lucky to get what little I have in this image: Link to comment Share on other sites More sharing options...
jpc Posted September 22, 2014 Share Posted September 22, 2014 Very Teredooid, this last photo. Sometimes you can find the remains of the clamshell in the tubes. Sometimes. Link to comment Share on other sites More sharing options...

Yes, but I am not sure if worms are the culprit...as JPC mentioned, clams can be found in the burrows.

Pilobolus Posted September 24, 2014 Author Share Posted September 24, 2014 (edited) Yes, but I am not sure if worms are the culprit...as JPC mentioned, clams can be found in the burrows. I'm a little perplexed on those because of the rugose surface of the burrow cast. Marine worms (at least the extant ones) don't seem as strongly ribbed and I imagined that even if they were strongly segmented, I don't think the pattern would appear as they moved through the mud.wood Absent knowing more about the ecology of these fellows, I thought the only way I could think of that ribbed pattern was generated was that the worms left a smooth track through the wood, but the early and late wood decayed at different rates as trees do when they undergo brown rot in the terrestrial environment. Would clams, perhaps, cause that feature? Edited September 24, 2014 by Pilobolus Link to comment Share on other sites More sharing options...

PFOOLEY Posted September 24, 2014 Share Posted September 24, 2014 (edited) ...even as I look at them now, I think my differential wood decay idea is snarge...LOL! You are asking the right questions...but there are other variables to consider. This is a marine environment...how does driftwood decay in saltwater? Does the salt preserve the wood, making it a home for creatures? Are the burrows for nutrients or safety?...and so on. Man, I have no clue. When I first encountered this wood, my imagination led me straight to worms as well. Edited September 24, 2014 by PFOOLEY "I am glad I shall never be young without wild country to be young in.

Indeed...where's a time machine when you truly need one? edit: I think the first time I visited the site, I just wandered about all within 100 yards of the eponymous windmill and found only impressions...I quipped to my fellow travelers that this must be where ammos spent the night during some migration. Makes me laugh now that I have learned how to look (and where). Edited November 13, 2014 by Pilobolus Link to comment Share on other sites More sharing options...
