Semi-micro fossils (echinoid, shell, bryozoans, others) from Aireys Inlet, Victoria, Australia (Oligocene)

[Oli_fossil]

Hi all,

 

Following up from my previous thread (https://www.thefossilforum.com/topic/139153-sea-urchins-sand-dollars-and-brachiopods-aireys-inlet-victoria-australia/), I returned to the same site (Aireys Inlet, Victoria, Australia) and closely inspected the fine, freshly eroded material on the sandstone platform/overhang (presuming ~20-25Mya), finding a number of interesting semi-micro fossils (1-5mm in size). Would appreciate any thoughts and ID!

 

Will post in separate posts for clarity. First off, this beautiful little echinoid, ~3mm in diameter:

No idea - distinct "double crescent" shape (~2mm):

No idea on this one - very regular ovoid shape with distinct "tick-shaped" groove, and layer lines reminiscent of what one finds on a cuttlefish bone, ~5mm long:

Bryozoan?

Coral?

No idea, like a little bead with two holes through it:

5, 6 and 9 look like starfish ossicles. 4 and 7 are foraminifera. Your shell is a brachiopod valve and the echinoid might be Fibularia.

12 most likely another Isididae. Other photographs are necessary, lateral shots.

Yes to bryozoan for 11.

Thanks - will try, I was having trouble balancing it vertically to get the other angle

Thank you for the IDs! I had no idea starfish ossicles looked like that!

Also found this little thing - smooth, with a squareish cross-section
