Crinoid calyxs and a holdfast.

[AllenAigen]

From an old collection, no data, may be from USA or Europe. The conical calyx has a two-inch diameter, a recessed attachment for the stem, and five very broad attachment points for arms.  the calyx has a hole through the center which is surrounded by concentric layers of shell so that, except for the central hole, it is solid (unlike any other crinoid I have seen or read about.)  The ovoid specimen is probably from the same locality.  It apparently also is almost solid, has five bowl shaped arm attachment points and an irregular central bowl.  The base is recessed but covered in limestone.  The holdfast is about 3 1/2 inches tall with a very irregular growth pattern.  All three have 'worm' tubes attached; the ovoid one has attached bivalve? shells and the holdfast and conical calyx have bore holes from exposure on the sea floor.   I need to move pictures from my phone...
