If you do not specify the extent_management_clause, then Oracle interprets the COMPATIBLE setting,
the MINIMUM EXTENT clause and the DEFAULT storage_clause to determine extent management.
If the COMPATIBLE initialization parameter is less than  9 . 0 . 0 , then Oracle creates a dictionary managed tablespace.
If COMPATIBLE =  9 . 0 . 0  or higher:

    If you do not specify the DEFAULT storage_clause, then Oracle creates a locally managed autoallocated tablespace. 
    If you did specify the DEFAULT storage_clause: 
    If you specified the MINIMUM EXTENT clause, then Oracle evaluates whether the values of
        MINIMUM EXTENT, INITIAL, and NEXT are equal and the value of PCTINCREASE is  0 .
        If so, Oracle creates a locally managed uniform tablespace with extent size = INITIAL.
        If the MINIMUM EXTENT, INITIAL, and NEXT parameters are not equal, or if PCTINCREASE is not  0 ,
        Oracle ignores any extent storage parameters you may specify and creates a locally managed, autoallocated tablespace. 
        If you did not specify MINIMUM EXTENT clause, then Oracle evaluates only whether the storage values
        of INITIAL and NEXT are equal and PCTINCREASE is  0 .
        If so, the tablespace is locally managed and uniform.
        Otherwise, the tablespace is locally managed and autoallocated.
