I recently visited the coast of Oregon and was able to beach comb along the Oregon coast from about Florence to just a bit north of Newport- an area spanning a short stretch of about the middle coast of Oregon. My sister lives along the coast there and she also loaned me her spare vehicle, "Greg the Van", for my adventures. I was particularly interested to visit Agate Beach located a little north of the Yaquina Bay area for agate and fossil hunting and I found a few interesting things from around there. The trip was planned late and I didn't have time to do a lot of self-education about t

Folks on mindat.com suggested asking this question here! This is less of a "what is this a fossil of" question and more of a "is this possible" question. I have a small chip of translucent chalcedony showing a mass of white inclusions, two of which look very much like a grass seed-head. The gist of the conversation so far has been 'is it possible for fossil material to be an inclusion within a silica mineral like agate or chalcedony?' As opposed to an agate-replacement or opal-replacement fossil like an agate limb cast, agatized wood or agatized/jasperized opaque mudstone with intact fos

Hello TFF, I purchased this relatively inexpensive specimen at Mineralfest this past fall, and I was wondering if anyone could tell me more about it. The seller informed me it could possibly be from Madagascar, but was transparent in admitting that she couldn't confirm for sure. It was with other pieces of petrified wood that were brown, but I was drawn to this one due to the red hues. I think it's agatized, and it looks "glassy," although there are too many impurities to shine a cell phone light through it. One side is polished, and I put water on the rougher backside to show mor -
Found in landscaping bed in south Texas I think it could be a solitary coral.

Found in a small Yellowcat wash, outside Moab, UT while scouring for petrified wood. Not near a uranium mine. Partially exposed and nothing else like it around the area all day. The wash was in Morrison material. About 3” x 5”. Super shiny even without washing. Thanks!

Hi guys, avid rock hunter here, brought home this “thunder egg” from crater of diamonds in Arkansas a few years ago. I finally got a slab saw and it’s not what I expected! It’s semi transparent in spots and some druzy inclusions. Some areas seem a little oolitic? Could it be an “agatized” fossil of some sort?

This fossil was found on a Gold Coast beach in 2019. I'm thinking Pliocene as it's like most of my beach fossil finds. It's a curiosity as it has some crystals inside the carapace. Any thoughts on this? Thankyou!

Some petrified wood found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation a couple of weeks ago. The cut slabs are from a log about 6-inches in diameter and my best guess is conifer only because most everything else in that area turns out to be conifer, specifically, Cupressinoxylon sp. Any other opinion about species would be welcome. There are several nice agate bands running through the length of the log and are clearly visible here. The first slab is dry and the second is wet.

Need help making an ID as to what I’ve found on the beach!
HaidaGwaiiBeachFinds posted a topic in Fossil ID
Hello All, I’m a newbie to this forum, subsequently solving my many fossil and rock mysteries. This one has me stumped. Surely it cannot be a fossil inside? Does that even happen? Also, it’s more defined than any other agate I’ve seen here (Haida Gwaii). Gosh, I sure hope this is an agate (please prove me wrong, if I’m wrong)! Thanks a mil. -
Happy new year. This is my first attempt at a post, so try and go easy. I respect the depth and breadth of knowledge in this forum. Thanks for yours in advance. Unfortunately I do not have a proper provenance for this specimen. This peice was purchased at auction with a rock lot, silified chalcedony (agate), and I was surprised at the symmetry and shape. My amateur mind brought me to fossil bivalve. Another specimen from the same lot shows this exact shape and general size, so here I am. What are your thoughts? Thanks again. 125mm x 115mm x 60mm 1216g

I found this agate on a beach in Northern California. It appears to have a flying insect trapped inside of it. Is this even possible? Or is it an illusion? Who would I contact to find out for sure?

The fossil I am posting today does not contain calcium. I does contain agate and my question is could it be a fossil stromatoporoid or stromatolite or something else?

I wish I could recall for sure where I found this. Most of my collection is from tide pools and coves on the West coast of the US but it could possibly be from Zion National Park in Utah, Kern River in CA, or a number of other places but those listed are most likely. It’s porous, lighter and slightly warmer than stone. The dark red areas are striated and softer than the rest. It does resemble some photos I’ve seen of agatized red horn coral, but I’m not sure. Any ideas or suggestions are welcome.

I found this on a rocky beach in West Seattle. Looks to be pretty transparent with a bit of banding. I assume it's just geological, but based on the size and shape I guess it could maybe be a bivalve fossil? SG is 2.61

I found this rock 50 years ago on the farm where I grew up in northern Illinois. The bedrock is far below the surface there. The surface rocks are erratics, dropped by glaciers that moved southwest from Canada through Michigan and into Illinois. It appears to be a kind of agate with some druzy quartz on it. I've recently shown it to several people and have gotten several different opinions on what it is and how it was formed, including that it is some kind of fossil. What do you think? The surface lines you see in some of the photos (most clearly in the third photo) are narrow and
