FossilDAWG Posted September 21, 2012 Share Posted September 21, 2012 Nice shells! Your "parasites" are barnacles, a different species from the single plate you posted a while ago. Also, I don't know if you were joking with the "bird skull" and "frog skull", but both are gastropods. The "beak" of the "bird skull" is a broken spine. You seem to have a really diverse selection of very well preserved molluscs at your collecting site. Don Link to comment Share on other sites More sharing options...
New Members cvi huang Posted September 21, 2012 Author New Members Share Posted September 21, 2012 Thank You Don! i am still try ID for "D-shaped hole" under the "gray gegologic formation" (under the snail-fossils) still gray layer, here lot of root-shaped (coral shaped?) with "D-hole" in slimer branch. this shape (D) not always D, can rectangle or circle or very slim D on top(?) of this thing can see lines of "slices" fragments are from only one thing (i broke while digging; the full shape is the drawing) Link to comment Share on other sites More sharing options...

New Members cvi huang Posted September 21, 2012 Author New Members Share Posted September 21, 2012 (edited) same "D-thing" before this post: http://www.thefossil...ce/page__st__20 very different but i think a part of same thing also same thing different part short blue, long red, (1,2,1,2,1,) it is sea plant?

Auspex Posted September 21, 2012 Share Posted September 21, 2012 I think they must be in-filled burrows, but I cannot explain the D-shaped holes...

AgrilusHunter Posted September 22, 2012 Share Posted September 22, 2012 My money is on a burrowing crustacean. Have a look at what the burrows of the modern ghost shrimp look like. The burrow systems can be quite large and complex, especially with a large population.

Auspex Posted September 22, 2012 Share Posted September 22, 2012 who can explain this? Those patterns, called "hackle fringe", are the way the material fractured.

New Members cvi huang Posted September 22, 2012 Author New Members Share Posted September 22, 2012 (edited) Thank You! but meaning is are not organic reason? 2,1,2,1,2,1,2 (is that long and short lines) very mathematical and under this fracture "centralized" lines and this very same with different regions i can not imagine that was a homogeneous hole? because a burrow naturally broke all, if it is hole why different type of lines, why not like a homogeneous? and "D" (here rectangle) hole in inner circle, with different material like metal (?) powder ok, Thank You really hackle fringe but why not one same logic, why are two or three different region on one slice? in circle, the white is organic? and why in center of circle if all cylinder is a hole? (the organic things and the hole why are not same size?) Edited September 22, 2012 by cvi huang Link to comment Share on other sites More sharing options...
Auspex Posted September 23, 2012 Share Posted September 23, 2012 I think the lines are very mathematical because of how the stresses propagated through the homogeneous material, and it is differences in the strength and angle of the stresses that result in the different patterns. As for the lighter colored center, that could be the result of darker minerals in the surrounding matrix migrating toward the center. I still do not understand the hole in the center, especially now that it appears that a different material is present there (though we need to be careful as to whether we regard that feature as a cause or an effect).

New Members cvi huang Posted September 23, 2012 Author New Members Share Posted September 23, 2012 (edited) Thank You Auspex! maybe this, Ophiomorpha nodosa burrow systems; however ichnofossils are very interesting top © is maybe same; and 'D' shape, (in cross-section) a rectangle, in D-image also maybe same Edited September 23, 2012 by cvi huang Link to comment Share on other sites More sharing options...

CH4ShotCaller Posted September 23, 2012 Share Posted September 23, 2012 Those patterns, called "hackle fringe", are the way the material fractured. I didn't know fracture patterns had a name, thanks. I had one that was very elaborate, thought it was a sea fan impression.

New Members cvi huang Posted July 31, 2013 Author New Members Share Posted July 31, 2013 (edited) UPDATE no hackle fringle maybe tipical same piece with same "hackel fringle" tipical D-shaped (C-shaped) hole, tipical flat discus forms, round slices tipical branching things all is same thing only different parts, different sizes? Those patterns, called "hackle fringe", are the way the material fractured. burrow systems? but how about this rarely preserved surface? most common things on riverbank no other fossil only snails Edited July 31, 2013 by cvi huang Link to comment Share on other sites More sharing options...
New Members cvi huang Posted July 31, 2013 Author New Members Share Posted July 31, 2013 (edited) Those patterns, called "hackle fringe", are the way the material fractured. Thank You maybe no fringe, found a new same!! piece with one long one short one long one short... lines softer part then under part in living time (or vice versa) 'D' shaped branching pipes can do this maybe Edited July 31, 2013 by cvi huang Link to comment Share on other sites More sharing options...
