Piedras_de_Tejas Posted June 8, 2014 Share Posted June 8, 2014 Here are some pics of an odd tube-like fossil i found on my first trip to the glen rose formation. if it helps, i found them in a layer packed with bivalve casts just a foot or two above a layer full of leptosalenia and heart urchins. I'm not sure if they're coral, burrows, or some type of stem, but I haven't a clue Anyone recognize these? My guess right now is some type of burrow... Cameron C.

Auspex Posted June 8, 2014 Share Posted June 8, 2014 Your guess is mine as well. The largest one shows the pellet-texture of shrimp burrows.

erose Posted June 14, 2014 Share Posted June 14, 2014 Burrows are fairly common in the Glen Rose. Auspex was right to point out the "pellet" texture in that large one. Crustaceans like ghost shrimp(?) sometimes made little balls of mud to strtengthen their burrows if the substrate was soft. Thye name for that type of ichno (trace) fossil is Lophiomorpha. Most burrows are hard to pin down to who made them but Lophiomorpha is easil;y identified as being from a crustacean since those critters still do this today.

Plax Posted June 16, 2014 Share Posted June 16, 2014 or Ophiomorpha? Also used to b called Halymenites if it's the same trace I'm thinking of Link to comment Share on other sites More sharing options...

erose Posted June 25, 2014 Share Posted June 25, 2014 or Ophiomorpha? Also used to b called Halymenites if it's the same trace I'm thinking of Yes, duh. Phat finger typing... Ophiomorpha Link to comment Share on other sites More sharing options...
Plax Posted June 25, 2014 Share Posted June 25, 2014 actually thought it might have another name, wasn't correcting Link to comment Share on other sites More sharing options...
Piedras_de_Tejas Posted June 30, 2014 Author Share Posted June 30, 2014 Thanks for all the great info y'all . Come to think of it i've encountered semi-cylindrical traces like this before, but i never knew what they were until the texture on these spiked my interest enough to make this post. Common or not, i haven't collected anything similar, so they are joining the rest of my "keep". Cameron C. "The important thing is to not stop questioning.
