These 2 items are cemented into a shrimp burrow from the Mooreville chalk, upper Cretaceous of central Alabama. Each one is about 2 mm in length. they don't resemble anything I'm familiar with. I was going to acid clean them but need to know if they are calcareous first. I'm hoping someone knows what they are. Also, can someone tell me how to draw lines on these photos to highlight features?

This came from the Jasper Creek formation, Bridgeport Shale, Missouri Series. Could it be a brittle star vert? I haven't seen them here before but I'm not sure what they might look like from the Pennsylvanian. Scale in millimeters.

From the album: Permian
One of the most common fossils from the Permian (this locality in particular). Unfortunately, they are almost always broken. Of the hundreds of teeth I have, perhaps only a few larger than a couple of mm are mostly complete. -
From the album: Permian
A handful of the more interesting (of very few) fossils I found in unprocessed matrix from the Archer City fm. here in TX. -

Eryops teeth are conical (this one bears no carinae, though don't know if that's true for the whole dentition), and often have basal creases. -
From the album: Permian
It's remarkable how much of an ecosystem's diversity can be captured in a space smaller than a matchbox. In this case are the likes of Dimetrodon, Eryops, Archeria, Seymouria et al.-

Actinopterygian (ray-finned) fish teeth from the Early Permian of OK (Wellington Fm.). -
From the album: Permian
An amphibian tooth from the Early Permian of OK (Wellington Fm.). They can be differentiated from similar Actinopterygian teeth by the lack of a conical acrodin cap (translucent tip), no "S" curvature, and basal creases which terminate well before the apex. The exact ID is uncertain, but it could be something like Trimerorhachis. -
From the album: Permian
Rhipidistian (lungfish) scales from the Early Permian (Wellington Fm., Waurika, OK). They can be identified by a "honey comb" structure on one side, the other is largely featureless. -
From the album: Permian
These sand grains were deposited by a river in the Early Permian of what would be North Texas. Iron oxides (e.g. hematite) color these sediments red (they weren't originally). -
From the album: Permian
Sandstone collected from the Arroyo formation (Clear Form Group) of North Texas. The color transition represents a transition between a river deposit (red) and a floodplain deposit (white). See "Geologic Guide of Baylor County, Texas" -
