DJ Fossil Posted April 12, 2011 Share Posted April 12, 2011 Found on Hornby Island, BC Local ident refers to a dentalia. What is the proper name for this beastie? Link to comment Share on other sites More sharing options...

Auspex Posted April 12, 2011 Share Posted April 12, 2011 I thought that a dentalium has longitudinal ridges; this seems to have, if anything, annular rings.

DJ Fossil Posted April 12, 2011 Author Share Posted April 12, 2011 I thought that a dentalium has longitudinal ridges; this seems to have, if anything, annular rings. that was my thought....I googled the dentalia images online and could find nothing even close to these. They are somewhat plentiful at this location, and all are about the same dimensions....but local lore as to identity doesnt suffice...and inquiring minds want to know.

Auspex Posted April 12, 2011 Share Posted April 12, 2011 I just did a Google Image search for cretaceous dentalium and found some examples (mostly from the UK) with similar structure to yours.

Wrangellian Posted April 14, 2011 Share Posted April 14, 2011 (edited) Some of our local dentalia here on the Island(s) dont seem to have longitudinal ridges, just fine growth lines. The ones from Hornby are Antalis cooperi according to Ludvigsen/Beard. Nice specimen! It looks a little glossy, though, like someone slathered it in diluted glue? which makes it difficult for photographing so that fine detail can be seen. If I douse anything in glue I try to dab off the excess so as to avoid the glossy finish. Edited April 14, 2011 by Wrangellian Link to comment Share on other sites More sharing options...
DJ Fossil Posted April 15, 2011 Author Share Posted April 15, 2011 Hello Wrangellian I had to re-assemble this beastie after it tried to self destruct. Removing the matrix was difficult. After all was rebuilt correctly, it was sprayed with a lite clear coat to stabilize it from changes in humidity. Unfortunately, it tends to be a tad glossy.... Thank you for the info, I always want to find the bottom line on a fossil's provenance. Cheers Link to comment Share on other sites More sharing options...

Thank You for your help there J. It was a fun day, although in the pics you looked less than happy with life.....wet feet will sometimes take their toll on ones attitude. Next time, YOU will score some huge ammonites from there! Cheers to my brother from another mother! Edited April 15, 2011 by DJ Fossil Link to comment Share on other sites More sharing options...
