Family: Micrasteridae LAMBERT, 1920

Micrasterid sp.

Pl. 3, fig. 4

M a t e r i a l: 1 test fragment, collection number FZP/P/12/2-3/023.

D e s c r i p t i o n: The fragment of echinoid test is flat and bears rows of small crenulated secondary tubercles and a short section of fasciola.

R e m a r k s: The above mentioned characters, together with shape of the test fragment, indicate possibly a plastron fragment of a micrasterid. Both the genera Micraster (L. AGASSIZ, 1836) and Diplodetus SCHLÜTER, 1900 which cross the Cretaceous/Palaeocene boundary may be considered.
