Found a nice crag whilst on a walk along the Rowthorne trail. It's an old railway cutting. Anyway, I found this. Is this a leaf fossil? I'll try get better pic when I'm home. Not sure of age of the rocks here.

Recently we had a quick exploratory trip just south of Sydney in search of Triassic fish and Tertiary leaves. Our first stop yielded a terrific but partially weathered nodule exposed in an outcrop of the Ashfield Shale. A clear layer was present in the cross section so it was likely to yield a fish! This is it after most of it was removed, unfortunately I don't have any before photos but the layer through the middle is clearly visible: Will include photos of the prep later in this post. Our next stop was the main focus of our trip but wasn't too eventful unfortunately. We drove around back roads looking for new outcrops of an unnamed Tertiary formation which sometimes yields very well preserved leaves and insects. We found a few outcrops of it but only one section of road yielded any good leaves. The site: A freshly broken rock with leaves: As soon as we got home I started on the fish nodule. The fish layer had already partially split which was helpful, but meant the inside was quite weathered and covered in calcium carbonate. Splitting the nodule carefully with a knife: A fresh split. Note the white calcium carbonate encrusting the surface: Soaking the pieces in acetic acid (8% vinegar) to dissolve away the calcium carbonate: The same piece I showed before after acid preparation, the fish are now clearly visible: Splitting the rest of the nodule: Reassembling after acid prep: The rock is a thick siderite nodule so is very heavy once all glued together. With pieces this large I usually make a spray foam cradle for the pieces to sit in, meaning I can disassemble it to move it around. Loosely assembled and starting with the spray foam: Surprisingly, this nodule ended up being packed with fish. The main large fish in the middle is likely a species of Elonichthys, but throughout the rest of the nodule are several other genera including Saurichthys, Cleithrolepis and Elpisopholis. Overall I can count just under 60 individual fish on this one rock, many are just small sections of scale pattern though. The Cleithrolepis is likely complete but sits underneath a couple of other fish, and the Saurichthys is tiny and incomplete but its long snout is unmistakable. The preservation in most of the specimens is poor, as with most other Ashfield Shale nodules, but the association of so many fish is of interest! One half of the nodule, I haven't quite finished the counterpart yet but it does have slightly better preservation. Note the partially exposed Cleithrolepis just in front of the pectoral fins of the largest fish: A small but particularly densely packed section: Will include more photos in coming days!

The leaf (5cm long) cames from Fumanya Sud site, in Spain. It's about 72-70 million years old. In geological context it is found in the Tremp Formation, specifically in the group called "Unitat Gris", also know as Gray Garumnian. Does anyone have any idea what species it's or what group it belongs to? Thanks. If you want more photos or information for a better identification, ask!

Hi, my 5year old son found this in Chile, near Cochamo in a riverbed and the more I look at it I wonder how a stone got this texture. Maybe you can help us understand how this happened. It is about 13inches long and very heavy. Thanks!!

Hi, I bought many years ago a Gingko leaf fossil, but unfortunately I lost the data regarding the name of the species and the location of discovery. Leaf dimensions: 5.5 cm x 4.2 (wxh)- Maybe someone can recognize the species a (and, possibly, site) from the picture I attach here? Thanks in advance, Fabio

A Few Recent Finds at Penn Dixie, a shallow marine Devonian Site in upstate NY
Biotalker posted a topic in General Fossil Discussion
Super folks and fossils! I had a decent trip to Penn Dixie with the experts recently and thought I would share a few finds. The first is the lower third of a crinoid calyx. I measures 4 cm and has an intact stem attachment segment. Aside from stems, its the first decent crinoid part I have found since 2015. I am fascinated by the geometry of the echinoderm organization- 6 around the stem, them 12 around the next whirl, makes we wish I had the entire calyx.- 8 replies

Hello all. New user from central Maine. I found what I believe to be a fossil in the stream in my back yard. I used an app to identify the rock as limestone. Limestone is not native to my area, but there is a source in nothern Maine about 250km away. If it is limestone I would guess it was deposited during the last glaciation of the Laurentide ice sheet. It looks like a plant to me, a whole leaf maybe. The raised " stems" are hollow and there is the round ball ont the end. This round ball has two holes which is why i thought maybe a worm. These holes are tiny and symetrical, but only able to observe them with a jewelers loop. Thanks for any info.

Hi could this possibly be a fossilized leaf? Or is it just my imagination. Found it in a creekbed near the Mississippi in Northern Missouri. Thanks in advance!

Hi All! I’ll get right to it…Found this out on a new construction site dig in north Oshawa, Ontario amongst other minerals and large boulders. Looks like it could be fish bones, but there’s a kind of leafy or veiny like pattern across the surface. Maybe part of a heart? Also, whatever the protuberances are have crystallized towards the centre and some appear to extend through the core and out the other side. No idea what I’ve found, but any info would be great!

Hi everyone, This is the first fossil plant I’ve ever found at big brook in NJ. I found an orange colored rock in the stream bed and saw some odd patterns hidden within. Later when I got home, I tried to take off a layer of rock, and to my suprise, there was a leaf impression. There were other plant impressions within other parts of the rock. I would love to know how old it might be, or if it is more recent and not a fossil at all. Thanks! FullSizeRender.mov

The tree fern genus Tempskya, known from worldwide Cretaceous deposits, was first reported from a North Carolina site in the February 1970 issue of the Lapidary Journal (article reprinted in February 1977 issue). A follow-up article on additional finds appeared in the January 1978 Lapidary Journal. The collecting site is now inaccessible and overgrown. Cut and polished trunk slabs show multiple roughly oval-shaped structures that are stems, surrounded by a mass of tiny roughly circular structures that are roots. Stems often have knobby projections that are budding leaf petioles, and free leaf petioles can appear in single or multiple horseshoe-shaped structures as the grow towards the trunk's surface. Photos show a collection of 31 of 40+ North Carolina slab specimens.

Hello all! In my hunt to find crab concretions I started out at the beaches of the Olympic Peninsula. I wanted to share what I have found! I have gone three times so far and the close to six hour round trip was a bit rough, but very well worth it and I can't wait to learn and discover more. I am struggling to find crabs, but I am continuing my research and hope to figure something out soon. If there is anyone that could point me in the right direction that would be greatly appriciated as well! The first concretion I opened, It took no effort to crack. I speculate it could be a piece of bone? Wood? A super lucky find, I cracked this open after returning home and found leaf fossil concretion! I believe that these are not common on the olymipic peninsula?? I think they are Oak? Quercus? I believe a bivalve? I was confused with this one, could this be a parital crab carapace? Or the shell of a snail? And lastly this claw. Is it shrimp or crab?

A few days were spent in the Green River Formation collecting fossil leaves and insects. Now comes the momentous task of identifying my finds. I have piece mealed together some information that has helped a bit. BUT by no means am I happy with my results. Does anyone know of a great guide or article which would help someone like me make proper IDs. Thanks, Mike

So I’ve just come back from the Barack and clean up what I found (removed all sand and gunk) and I had come across some shells, unusual crystals (probably quartz) and a fossil leaf and stem imprint (for size the red shell is around the size of the average hand) If anyone has any info on any of these would be a big help
