Micraster brevis (DESOR, 1847) is right, comes from lower Santonian, Place where you cound find them was the region around Olazagutia , Navarro-Cantabrian Basin, northern Spain.

We've been sitting in the Ordovician for about two days.  I'll get us rolling again with this:

 

Lepidocyclus capax

Late Ordovician

Liberty Formation

Now Hiscobeccus capax. 

See Amsden 1983 p.37 

 

This thread is wonderful, I'm having a great time catching up with it and drooling a lot.

 

Here's my Ordovician contribution

Two lovely atyrpids; Anazyga recurvirostra, Verulam Formation, James Dick Cement Quarry, Gamebridge, Ontario.

Atrypa reticularis newsomensis, I think. 

 

Here's a related, tiny Atrypina disparilis also from the Waldron Shale of Indiana.
