piranha Posted October 20, 2014 Share Posted October 20, 2014 These are actually chondritid (Chondrites isp.) feeding traces. Congrats on finding a spectacular example! Quote Chondritids: This is one of the most common and distinctive groups of trace fossils. Ranging from the Ordovician to the Tertiary and to modern deepsea muds, chondritids are found in turbidite series as well as in shallowmarine shales and even in storm sands. So one may assume a heterogeneous origin. Yet the different forms share not only a plant-like kind of branching along bedding planes (hence the term “fucoids”), but also a preference for relatively quiet and low-oxygen environments. Like the other forms in this chapter, chondritids are clearly feeding burrows (fodinichia), but details of the probing, feeding and backfill processes are less uniform and must be analyzed separately in every case.

Brewcuse Posted October 20, 2014 Share Posted October 20, 2014 Nice looking find! What part of CNY? We can narrow down the age by geography. Link to comment Share on other sites More sharing options...

Brewcuse Posted October 20, 2014 Share Posted October 20, 2014 That area is Silurian and Ordovician, depending on the exact formation. The Clinton Group is type-named for a Silurian outcropping in the area. Link to comment Share on other sites More sharing options...

Plax Posted October 20, 2014 Share Posted October 20, 2014 have seen paleophycus/arthrophycus in the Tuscarora Quartzite that look similar but have never seen anything on this small scale and so distinctively differentiated from the surrounding sediment. The Tuscarora material is in massive blocks big as a car sometimes with traces a couple of inches wide. What would well preserved colonies of coenites look like? Not saying that is what this is just trying to get my head around the trace being so distinctive from the sediment. Link to comment Share on other sites More sharing options...

tmaier Posted October 20, 2014 Share Posted October 20, 2014 What happened to the image? There is something funny about it. I had to re-hit the thread three times and click on the series of numbers to get the images to show up. I'm not sure if the problem is with the image file or the browser or the server. Odd, but I see it now. Link to comment Share on other sites More sharing options...
morgansilk Posted October 20, 2014 Author Share Posted October 20, 2014 "One never knows, do one" == Fats Waller "Things come and go so quickly here." == Dorothy Thanks, everybody. It's a small layer, mostly continuous, that's differentiated from the strata above and below.There are probably huge slabs, but they are under a lot of hils and trees! This was surrounded by other larger and smaller chunks that fell out. The cliff is precipitous., so not to dig. They are cool. First I thought they were fossilized frost-- because I wanted it to be. I love environmental-type fossils, like wave action etc. Link to comment Share on other sites More sharing options...

Shamalama Posted October 21, 2014 Share Posted October 21, 2014 Very cool fossil! They almost look pyritized to me. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Wrangellian Posted October 21, 2014 Share Posted October 21, 2014 Spectacular for sure (I find myself saying that a lot here on the Forum but not usually with inchofossils)! I'll bet others would like some samples even if smaller pieces, don't let them get buried and forgotten. Is it a well-known collecting site?

(1996) Trace Fossils: Biology, Taphonomy and Applications, 2nd ed. Chapman & Hall, London, 361 pp. the color difference is bothering me not the 3-D aspect, guess it could be weathering. I agree that these look like chondrites, would still like to see a sharp close up of a single limb if possible. Link to comment Share on other sites More sharing options...

morgansilk Posted October 21, 2014 Author Share Posted October 21, 2014 I have this more dramatic one, but I can't remember where I got it altho it has to be central NYS, because I fossil hunt while visitng my aged parent every year. However, it sure looks wormy. Link to comment Share on other sites More sharing options...
Wrangellian Posted October 21, 2014 Share Posted October 21, 2014 Nice, but I like the first one better. Probably some kind of worm produced these both but we only name ichnofossils based on their form rather than on what probably formed them since that is usually impossible to tell for sure. Btw, Make sure you record the location of all fossil finds as accurately as possible! If you 'check out' unexpectedly and leave no record of this, the fossil is 'orphaned' and less useful to science and less valuable to the next collector who might acquire it.

Plax Posted October 27, 2014 Share Posted October 27, 2014 your last posted pic looks like what I know as Paleophycus or Arthrophycus. Rock looks like quartzite also like the Tuscarora. Could you please take a sharp photo of your first one close up and post it? Would like to see the texture. Much obliged. Link to comment Share on other sites More sharing options...
