| NHMUK R8699 and the holotype of Th. bruntrutana (MJSN SCR011-87) have several features in common. Although NHMUK R8699 is only about 65% the size of MJSN SCR011-87, both specimens have vertebral scales of the same proportions (about twice as wide as long) and shape (clearly longer anterolateral sides) | ||||||||||
