I am pretty sure that I commented on one of your photos but now can not find it, my app hasn’t been working right. This is going to be some sort quartz/chert rock. If you look at it with a handles can you see grains? They may look like circles but they could also look like blobs. If you do then it is a really cool quartzite!

The shape tells me it was some sort of brachiopod or bivalve but the patterned holes seem to be chamber wall within the shell similar to coral have… I am not sure but very interesting! It has defiantly been broken at an awkward cross sectional view but that’s what makes it really cool!

Okay, everyone needs to simmer down. First off people on a free app should not have the power to insult your self worth, it is up to you what you read and you have to remember that a lot of context is left out when all we have to work with are just comments. There are people on this platform who are amateurs, there are people (like myself) that…[Read more]

Sorry for the late response, school and work. It can be a killer! It could be a vast number of things but if it were quartz it would be able to scratch a piece of glass. I am not sure what you mean by real/fake, as if natural or lab grown?

These are burrows! They are called fucoidal because they were originally thought the be kelp. There is debate on whether they were formed by trilobites or by poorly preserved worms. Here’s a link about them in Utah: https://www.waymarking.com/waymarks/WMFQ7F_Fucoidal_Quartzite_Logan_Canyon_Utah

Looks like shell growth to me! They could be the ridges of a shell: clam, oyster, brachiopod, and so on

So it blocky?

All I see is a hunk of chert…

They nick named them Roman lanterns because they look like old oil lamps

A beautiful pecten clam! One of my favorites 😉

Great find! I am so glad to hear he is excited!! Hopefully he finds many more!! ☺️☺️

Is the fools gold flakey/platey? If so then it is a type of mica called phlogopite!

Specifically a pecten clam!

I believe it is actually horn coral in cross section

Hello! I have to agree, not a plant. It is much more likely to weathering but still cool! As to the type of rock and why I am not entirely sure. It is hard to tell from a photo. It kind of looks like reef rock I’ve seen…

@mackenzie-smith wow! Thank you!!

I have made several thin section this fall and it’s definitely a comfier of sorts. I’m leaning towards a bald cypress, it’s on the coasts of the Cretaceous Interior Seaway. Thinking it’s a storm deposit because all logs but no roots or real leaves yet. Thanks for responding though!!

Here is a half decent website that tells you about some of the variations! It is so complicated that your head will spin sometimes 😂😂 http://www.geologyin.com/2016/04/major-varieties-of-quartz.html?m=1

@a-trilobite Haha! Thanks I’m glad I could clear it up for you! Quartz is the mineral of MANY names. Not only can it hold trace elements but also water so there is a whole slide bar sort of scale of what to call it if it is this percentage of water. For example chalcedony has a decent bit of water which makes it not as hard as quartz but opal h…[Read more]
