A few recent finds(Brassfield Formation)

[bmoviefanatic]

The first two pics are front and back view of a brachiopod on what I believe is some kind of coral. The stalk in pic 3 is about 1 1/2". The fourth pic is light, airy, and has a red stalk inside that you can see in the photo. It is pretty weird. The brachiopods in the last two photos are about 1 3/4" each.

In the first two pics, i think you have another kind of bryozoan than coral.

The third pic (long white segments) looks plant-like, owing to the surface texture. I think I saw another post like this recently.

Thanks guys, I'll take both answers and be happy.

What's up with that red structure in the granola cluster sitting on the sushi mat?

Any chance getting a macro or hand lens shot of it?

What's the cluster made of? Shell hash?

Picture 3 looks like a horse tail. It is a plant that does not look like a horse tail. But that should not be embedded with bryozoans and brachiopods,

I'm pretty sure photo 3 is a bryozoan.

[fossilized6s]

i agree with John. Bryozoan, possibly something similar to Leioclema.

[Shamalama]

Yup, I'd say Bryozoan for pic three as well. The segmentation is interesting though. I don't think I have seen anything like that in the Silurian before.

Hi!Nice fossils !

My thoughts:

1st, 2nd and 6th pic- rynchonellid brachiopods.

3rd-Bryozoan, because you can see the holes where the zooids (each member of the colony) lived:https://en.wikipedia.org/wiki/Bryozoa

5th-orthid brachiopod.

Regards,

P.S-Just a curiosity: brachiopods and bryozoans have both a lophophore, wich is an organ used for filter-feeding:https://www.britannica.com/science/lophophore

Craig,

That orderly surface of holes in a net-like structure is normally a sign of bryozoa. Bryozoa can be branching like seen here, or in a fan shape, or a surface encrustation on some other object.

Some corals can look like this, but this one here looks like bryozoa.

EDIT:

Also, consider its association with the other marine specimens.

Very cool finds! The third picture looks like there are bits of coral in the matrix, or more bryozoans... probably not a plant. They are all very cool! Love the brachiopods!

1,2,5 and 6 are Ordovician brachiopods (1,2,6 are Platystrophias; 5 is Hebertella) . brachs 1 and 2 are on bryozoas. Pix 3 is bryozoa. Can't tell what pix4 is. Pix 3 and 4 look like Brassfield LS, the rest is Richmond Formation.

[abyssunder]

Herb is correct.
1,2,6 - looks like Platystrophia sp., 6 - possibly P. ponderosa (my guess)
5 - Herbertella sp.

3 - Bryozoans, I agree with the others.

Also agree with Herb. Are you are getting into Ordovician float from down slope? The Brassfield is usually a stark contrast from the Ordovician below. There is a Brassfield Platystrophia species but it does not match your specimens in those photos.

PS As you get to know corals and bryozoans, one of the main differences is in the size of the little openings, In bryozoans they are called zooids and are always very small. Fractions of a millimeter across. By contrast the corallites of colonial corals are almost always larger. Generally well over a millimeter if not two or three. There are one or two "corals" such as Tetradium that have very small corrallites but they are the exception. This is also one reason it is so important to somehow include an object or an actual scale in each photo when you are asking for identification help.

the Brassfield LS is normally a yellowish brown crystaline limestone, often criniodal. Most of the Ordovician is gray shale or limestone. In general.
