Dill Posted April 29, 2016 Share Posted April 29, 2016 Hi I posted earlier some newbie trace borings/tunnels fossil photos and got great info. I have this other piece to share. I'd appreciate any input on what you think it might be. It's the same white material (dolostone?) but with a brown cherty line. I have found many of these bored rocks washed up on the same Maine beach. The photos show both sides - one has bottom-filled borings (They are sealed at the bottom). The rock is in my palm. Thank you for all your expertise & any info you might have. Link to comment Share on other sites More sharing options...

ynot Posted April 30, 2016 Share Posted April 30, 2016 Sometimes it takes a while for the right person to see the post, be patient and one of the experts should chime in eventualy.

Guguita2104 Posted April 30, 2016 Share Posted April 30, 2016 I think it's just a weathered sedimentary rock (natural erosion) 1 Link to comment Share on other sites More sharing options...
Dill Posted April 30, 2016 Author Share Posted April 30, 2016 I think it's just a weathered sedimentary rock (natural erosion) Not sure I understand but glad for the response. Pretty sure it's chert w a cortex or limestone w a chert line. Do you think part of the cortex got rubbed off and this is a chert stone? I'll post new pix. The borings are also part of my interest in relation to the brown line. Link to comment Share on other sites More sharing options...
Dill Posted April 30, 2016 Author Share Posted April 30, 2016 It's a tri-faced shape. Brown line on face #1 borings on face #2 and no marks on face #3. Hopefully these photos are helpful. I have more but it says they're too big to load. Link to comment Share on other sites More sharing options...

Guguita2104 Posted April 30, 2016 Share Posted April 30, 2016 (edited) And for that I didn't understand very well what you were trying to identify in that rock. Edited April 30, 2016 by Guguita2104 1 Link to comment Share on other sites More sharing options...
Dill Posted April 30, 2016 Author Share Posted April 30, 2016 And for that I didn't understand very well what you were trying to identify in that rock. You are doing fine - it's me who is confused Others had a discussion with me earlier about trace fossil tunnels being "filled in" and I thought it could be a filled trace fossil burrow given the two borings. Or maybe it's a fossil of a worm. Or maybe nothing. Link to comment Share on other sites More sharing options...
tmaier Posted April 30, 2016 Share Posted April 30, 2016 What I would do if it was mine is that I would pick away the limestone/dolomite to expose more of the object, or extract it totally. It does seem to be "something", but the shape does not ring a bell. 1 Link to comment Share on other sites More sharing options...
doushantuo Posted April 30, 2016 Share Posted April 30, 2016 (edited) any chance 08348 is due to a pebble rotating in a cavity though wave action? Paramoudra,anyone? Edited April 30, 2016 by doushantuo 1 Link to comment Share on other sites More sharing options...

It does seem to be "something", but the shape does not ring a bell. Could it be a filled in worm tunnel given the two borings on the opposite side? I'll dig a bit, any suggestion on a tool? Screwdriver? Link to comment Share on other sites More sharing options...
Dill Posted April 30, 2016 Author Share Posted April 30, 2016 any chance it's leftover evidence of eolian erosion?I found this in an area where lots of chert washes up. Not sure if it's native or ballast. I pick up everything that looks interesting....One piece has the same "rootbeer" color but not as defined as the piece discussed here. That second piece has no borings. Link to comment Share on other sites More sharing options...
ynot Posted April 30, 2016 Share Posted April 30, 2016 The holes are most likely from a boring clam and are recent additions to the rock, Tony Darwin said: " Man sprang from monkeys."

Auspex Posted April 30, 2016 Share Posted April 30, 2016 The holes are most likely from a boring clam and are recent additions to the rock, Tony I agree; piddock clams, likely. 2 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!
