Identification of a new mineralized tissue in the notochord of reared Siberian sturgeon ( Acipenser baerii )
International audience In a study aiming to improve knowledge on the mineralization of the axial skeleton in reared Siberian sturgeon (Acipenser baerii Brandt, 1869), we discovered a new mineralized tissue within the notochord. To our knowledge, such a structure has never been reported in any verteb...
