After a little research I think this is coprolite. Rock on one side and something that resembles poop on the other side. See next post for reverse side. Size is 1 1/4 inch by 3/4 inch by 1/4 inch

So is this rock considered a trace fossil or a fossil at all? I am asking because I have seen similar rocks identified as fossils. Thanks.

This is a steinkern of a fossil clam that I had purchased, the shell itself fell apart almost immediately and this was left. I just want to confirm that the things on the surface of it are some kinds of trace burrows from worms, I am not really sure but that is what they look like to me. Thank you all.

Found this slab at Jalama Beach, California on Saturday. It was quite different from all other blank pieces we found. Monterey Shale Formation, Miocene. Some of these prints look like bird tracks to me. Any insights?

Looking for help identifying what I believe are trace fossil found on the cliffs in Kilkee Ireland. The area is Upper Carboniferous if I am reading the map correctly. Any help would be appreciated.

Nice example of Scalarituba found yesterday as float in NE Ohio. I would like others to confirm my identification. Thank you!

Quartzite Flat Rock with Pattern, Man-made or Natural?
Bronzviking posted a topic in Rocks & Minerals
Hi, I found this odd rock on the beach and it looks like quartzite with an odd grooved pattern on one side. Size is 1 3/4 x 1 1/4" and almost a half inch thick. My first thought was a tile with a white designed background. Is this pattern formed naturally by erosion or man made? What do you think this is?

Hi all, I have a pair of dino tracks. The left one is a Grallator sp. from the Connecticut River Valley. The right one is an Anomoepus scambus from Granby, Massachusetts. I've been trying to figure out their formation. I know they come from the Newark Supergroup. I would like to narrow it down. Do they come from the Portland Formation?

Okay, I had originally just thought this specimen was a 'mother nature playing games' kind of rock when I was out exploring on a day that turned out to be filled with lots of trace fossils. After some online research for Ordovician trace fossils I came across some Flickr photos for Petroxestes pera, bivalve borings, that were once called 'turkey tracks'. The particular photo panel labeled, Petroxestes pera bivalve borings on limestone hardground (Turkey Track Layer, Waynesville Formation, Upper Ordovician; Flat Fork Arm of Caesar Creek Lake, Warren County, Ohio, USA) , looks quite similar to the strange marks I found in this upper Ordovician formation here in southern NM. Any trace fossil turkey track experts willing to comment? Thank you in advance, Kato

Was digging up a part of the yard with lots of chert scrapers we found and thought I saw something. Mud was wet so wasn't sure. After it dried I found these inside. Is this something or am Crazy?

Here is a fossil shell I found on a fairly recent trip to big Brook nj, towards the right there is a burrow that looks very straight and in the end of one some kind of dark conical figure is located, not sure what it is, any help would be appreciated. Thank you.

Cottowood Mbr, Beattie Fm, Council Grove group, Permian. Western Greenwood County, Flint Hills, Kansas. I've found 6 of these in only in this one place. They are most likely the interior molds of the actual trace. They were discovered over a period of several months. They were found as tumbled out, not in situ. I'm inferring what's top and bottom due to some obvious features and basic physics. Some retain what appears to be an original edge around the top. The top diameters range in size from 5" to 10+", with heights from 2" to 6". These were found in an area disturbed by oilfield work where it looks bulldozed out for some purpose. Geologically, the area may have intermittently been shallow or shoreline. I've done an amateur's inventory of fossils in the immediate area and found highest numbers are of very! small bivalves.

Good afternoon everybody! During a fieldtrip in Silesia (Poland) last year I visited a rather large spoiltip looking for plant fossils. The spoils left behind by the mining company indicate they still use (or used) the old method to separate the coal from the surrounding debris, allowing the coal to be 'baked' (e. g. the presence of pyrite that turns into sulphuric acid -h2so4- under the influence of wind and rain, ...) something typical for the majority of spoiltips I visited in Western Europe. Unfortunately I have no detailed geological data on the age of the debris in the spoiltip but there is no doubt this is Silesian (upper Carboniferous) in age. I even tend to think this is Westphalian in age based on the fossils found, but let's keep it to upper Carboniferous to be sure. I found several species of Lepidodendron, some Eusphenopterids, both Stigmaria ficoides and S. stellata, etc... And this never-seen-before 'thing'. My initial thought was that this could be some sort stem/branch but, in my 20 years of collecting Paleozoic plants, I have never seen the repetative triangular pattern that covers the branch (or tube if you like). Perhaps this could be some sort of tracefossil? Since my ichnofossil-knowledge is extremely limited someone here can help me out? The height of the 'tubes' varies between 2 and 3mm. Have a nice day!

Hellow Guys, I have the doubt, the trace fossil of the picture is a rhizocorallium, diplocraterion or taenidium? Or none of those three?
-
Hi all, I recently have found trace fossils called Rhizocorallium. It is possibly from the feeding burrows of a Crustacean, annelid type creature. Found in the ~90 million year old marine shallow seas of the Cretaceous period contact between the Austin chalk and Eagleford shale formations. These are very small ones. From the Martin Marietta cement quarry phosphate layer siftings.

From the album: FreeRuin's Finds
Either a small footprint or a partial one I believe it to be a Grallator due to its shape and size. Picked it up while hiking. Hartford Basin Portland Formation Massachusetts -
Hey all: For your consideration and expertise, an ammonite partial collected by the poster's parent has some interesting features. I don't know the exact formation of origin, but within the Rio Puerco river valley known to be Cretaceous period. I'm posting the best images I have at the moment, which, in addition to the partial with the scale cube (lower ammonite partial), are my attempts at using a smart phone to shoot down the dissection scope tube with the ocular removed...It's the best I can do at the moment. In question are the egg like features you can see on the partial. Most ammo eggs I have seen are spherical and not bacilli-like. The black dots are lichens that are commonly found in area rocks, usually in small crevices that trap dew. Thoughts?

Hello all, I found this piece about a couple months ago while searching for dinosaur prints in cretaceous siltstone. I'm not sure what it is, it is raised and could potentially be some type of depositional feature or erosion pattern. What do you think?

Found these beauties in my neighborhood on a sidewalk I've walked over for about 15 years... Any ichnologists out there? I'm thinking Cosmoraphe, but I'm a bit out of my depth.

Hi all, I was wondering: would the steinkern of for example a Turritella be considered a fossil or an ichnofossil? Because in fact, the shell itself didn’t become a fossil, and what we are looking at is just sediment that filled in the shell and then solidified. But then again I’ve never heard of a steinkern being referred as an ichnofossil... So what do you guys think: really a fossil, or just a trace fossil? I am curious to see everyone’s opinion Best regards, Max

From the album: Starting at the Beginning
Beach finds I'd kept prior to becoming truly interested and adopting this as a hobby all surrounding a trace fossil that was one of a handful of pieces found 4 months ago that turned me into a real rock nerd! I liked how they look as a set, so I framed them and hung them on my wall. -

Footprint? New Jersey Late Triassic/Early Jurassic Continued
Kurufossils posted a topic in Fossil ID
Hello, this is a part 2 of my last thread with some of my other finds that I've found this at a site in new jersey where some footprints have been found from the Late Triassic/Early Jurassic, I am unsure about if these are footprints of sorts, any help will be appreciated thank you!.thumb.jpg.199bfe7f0722cff28ed302cdfb98578d.jpg)
