Petrified Wood with what looks to be cuts in it
ImmaFrayedKnot posted a topic in Questions & Answers
I found this beautiful piece today along the Arkansas River bank in Colorado. I have a few other pieces of petrified wood but this is the largest that I've found and it almost looks to have been cut with something before hardening. Just curious if this is usual. The cuts are not very deep and I've tried to get the best pictures I can of them.- 2 replies

Hello all. I'm a rock and mineral guy but am becoming more interested in fossils and have been able to fossil hunt in a few states over the past two years. I was hunting on the Peace River after a business trip two weeks ago and The Fossil Forum kept coming up as I was discussing credible, well respected resources with a few experienced individuals in the river with me. I'm looking forward to increasing my fossil knowledge and plan to use this forum as one way to do that. Thanks in advance for everyone who is willing to share their knowledge, whether here or elsewhere.

I recently collected quite a few artifacts from a privately owned piece of property located in the Debeque Colorado area. I beleive most of the pieces (knives, drills, hand axes, projectile points, ect.) to be of late Paleo Indian Age. Specifically, Foothills Mountain Complex. A significant portion of the artifacts were knapped from source material that contains the fossil type represented in the photo. I cannot identify the species. I find it very interesting that tool stone containing this particular fossil was apparently utilized over the same material without this fossil. Tool stone containing this fossil is very difficult to find. Stone with no fossil is easily obtained. This could indicate they wanted their tools to have this fossil within them. Why? I would love it if someone could tell me what this thing is. The Geologic maps I can find online indicate the entire area could be the DeBeque\Wasatch Formation. Any information would be more than appreciated. I have numerous additional photos but this one is by far the most detailed. Thank You.

Little slice of heaven near Fort Collins with some nice Inoceramus Clams. Usually try to not bust open big rocks like this and instead find ones that have already eroded out but this nodule had a crack running along really nice bivalve so I couldn't resist.

Good day everyone, I was out over by the Ratone Plateau, not too far from the purgatory river, and came across these fungi like fossils. I have only heard that mushroom fossils were only found within amber but my father was thinking they were actual fungi fossils. What do you all think? They kind of look like the caps of mushrooms. Any help identifying what these are would be greatly appreciated. Thank you

Inoceramus valve resting on top of a Placenticeras ammonite
rawfossils posted a topic in Member Collections
A cool piece frozen in time from the day they were buried together. Also a decent size Inoceramus shell for the area and always fun to find an ammonite. This piece is from Boulder, Colorado. -
I was wondering if there's anyone (preferably in Colorado) who can prepare fossils with an air scribe if sent to them and if so what there prices would be for a project. I have a plethora of fossils from the Pierre Shale still encased in matrix and a hammer and chisel is just not detailed enough and it requires breaking and glueing specimens. Hopefully one day I can get my own air compressor and scribe setup but for now I'm in a apartment and that's just not possible. Any feedback is appreciated.

My first fossil hunt and the Inoceramus that ignited my interest in fossils
rawfossils posted a topic in Fossil Hunting Trips
I was really enjoying hiking around different spots in Boulder, Colorado and eventually I came across a beautiful outcrop of the Niobrara Formation. I thought it was so cool that there were shell imprints in the rock and nobody had ever taught me about the Geology of the area and it was really fascinating to see for myself that the whole area was once under the sea. I stumbled upon a massive Inoceramus and I knew I had to haul it home. Not bad at all for a first fossil hunt I don't think I ever found a Inoceramus as impressive as my first. Begginers luck. -
Hello, Could I get some help identifying these two nautiloid steinkerns? Unfortunately no precise age/locality info on them but I think they might be from the Pennsylvanian or Permian of Kansas or Texas. They are both around 8-9cm wide. 1. 2. Referring to this: http://inyo2.coffeecup.com/kansasfossils/kansasfossils.html I think #1. might be Metacoceras and #2. might be Liroceras. @Missourian I believe you are referenced in that post and you seem to be experienced in this fauna? Thanks

Any thoughts on this fossilized bone found along a lake shore in central Colorado?
Ig Kneeuhs posted a topic in Fossil ID
Came across this fossilized bone along a lake shore in central Colorado, a little southeast of the Denver metro area, and was hoping you all could help ID it. My initial thoughts were that it belonged to a prehistoric mammal of some kind but I have very little experience identifying specimens like this.. Also, I'm not sure if this is useful information or not since it was found in the sand by the water's edge, but petrified wood fragments were scattered around the area as well. Any posits will be much appreciated, thank you! -
Never seen anything like this so far. I know it's an Inoceramid from the shell structure but I've never seen one in this shape before. I know there's a lot of variety with this species but I have a lot of experience collecting bivalves and I've never seen one like this.

Fossil Insects from the Eocene Florissant Fossil Beds (Teller Co, Colorado)
Opabinia Blues posted a topic in Member Collections
Being a Colorado native, I have taken multiple trips to the public-access Florissant Fossil Quarry located near Florissant Fossil Beds National Monument in Florissant, Teller County, Colorado. This quarry provides fossil collectors fantastic access to the shale layers of the Florissant Formation, a late Eocene (Priabonian, ~34 million years old give or take) lagerstatte known for its diverse fauna of fossil insects, in addition to plants, gastropods, and very rarely vertebrates. Most fossils occur in very thinly laminated ashy grey shales. Other lithologies present include well-sorted tan course sandstones and well-sorted grey claystones. A lacustrine depositional environment is apparent, and though the Florissant Formation has previously been interpreted as the remains of a single large lake (the retroactively named Lake Florissant), it is now generally thought that deposition occurred across several smaller lakes, which of course shifted in their exact location throughout the period of deposition. This thread is for me to share some of my better quality (or more interesting) fossil insect finds from the Florissant Fossil Quarry, and to allow other people to share their Florissant insects. I intend on updating this thread as I make more collecting trips. Most insect fossils found at Florissant are of poor quality, however exceptionally beautiful specimens do crop up quite frequently. Regardless, identification even down to family level is usually very difficult, and some specimens I even have difficulty assigning to an order. Additional reading: https://bioone.org/journals/palaios/volume-27/issue-7/palo.2011.p11-084r/DEPOSITIONAL-SETTING-AND-FOSSIL-INSECT-PRESERVATION--A-STUDY-OF/10.2110/palo.2011.p11-084r.short Please note that at least for now picture quality is not ideal. I do not have the capacity to take good quality macro photographs, but I am doing the best that I can. The scale of the ruler is millimeters, magnification (when applicable) is noted. Order Diptera (True flies): Probably my best-preserved Florissant insect (and one of the first ones I ever found). Another fly. I'd like to be able to identify this one to family (and it almost certainly is identifiable to family) but I haven't been able to place it. This is a gorgeous fossil! Magnified 20X under a stereo microscope. Another gorgeous fossil fly. Possibly a gnat (suborder Nematocera), but I'm not 100% on this identification. Partial fly of indeterminate family, most of the abdomen is apparently missing. Both wings are preserved, the thorax and head are also nicely detailed. This is an example of a march fly (Family Bibionidae), probably the most common insect at Florissant. Many specimens (such as this one) are preserved without their wings. The head and mouthparts are very nicely preserved here, I feel shameful that I could not manage a better photograph. Crane fly, (Family Tipulidae). The preservation quality is not fantastic, but the gross anatomy can be easily made out (both wings, the abdomen, thorax, head, eyes, and even the halteres and some of the legs are present). Order Hymenoptera (Bees, ants, wasps, and relatives): A nice solitary bee (clade Anthophila). The details are not as high-fidelty as some other Florissant insects, but a nice complete specimen. Order Hemiptera (True bugs): Magnified 20X under a stereo microscope. A shield bug (superfamily Pentatamoidea). This is a really neat specimen because fossil Hemipterans aren't particularly common. Indeterminate Order: A large insect that I've never quite been able to place. Two wings are very faintly preserved which would normally be indicitave of a fly, but this specimen just doesn't look much like a fly otherwise. The antennae are interesting, it's a very large insect, and the tibia has an interesting flange. Unfortunately I can't seem to get a good look at the mouthparts (which has been very useful for me in the past for identification). Magnified 20X under a stereo microscope. At first I thought this might be an ant (family Formicidae) but under magnification the shape of the head is more suggestive of a fly. Very poor preservation, I'm not confident I'll ever get a solid answer here. Larvae: A nice plump fly larva, looks to me to be from a botfly (family Oestridae) or a relative. A very strange fossil. The segmentation and tagmosis definitely means this is an arthropod of some sort, and an insect larva is my current interpretation. Still, I've never seen anything quite like it. I've had a few people suggest to me this might be the abdomen of an earwig, but that's definitely not the case (earwig cerci do not look like this or articulate with the abdomen in this manner). Non-Insect Invertebrates: Just an example of one of the tiny gastropods that are common. It takes a keen eye to see them, but once you can recognize them you realize they're very plentiful. If you have some fossil insects from this locality in your collection, feel free to post them here too! Cheers!- 10 replies
