Are there any other hollow meteorites out there? ;)?

This is does not look at all like a meteorite. It looks
like a classic example of an ordinary hollow hematite
/ goethite concretion, which is common known
by rockhounds as either ?Indian paint pots? or
?rattle stones.?

For examples, see pictures in ?Goethite? at:

Concretions of Garvies Point

I have seen outcrops in Louisiana, i.e. the sand pit at
Eddie Jones State Park, Caddo Parish, where numerous
concretions identical to this eBay specimen had eroded
out and were eroding of the ground by erosion.

Some random papers about such concretions are:
