Asymmetry in an Ordovician conulariid cnidarian
Original language description
Conulariids have cone-shaped skeletons normally show perfect tetraradial symmetry. However, in the Ordovician species Metaconularia anomala (Barrande 1867) from Drabov (Czech Republic), tetraradial symmetry is compromised in three ways: (1) the skeletonoften shows torsion; (2) the four sides may vary in width at the same level within one individual; and (3) one side may be deleted to give a triradial skeleton. Almost 2000 specimens were studied in museum collections. It is speculated that the signalling protein Nodal as well as Hox-like genes were involved in controlling the asymmetries described in M. anomala.
