Isn't Metriacanthosaurus related toDimetrodon?—Precedingunsigned comment added by24.141.20.9 (talk)21:34, 3 February 2009 (UTC)[reply]

Not particularly.Dimetrodon is a pelycosaur, an early entry on the line leading to mammals, whereasMetriacanthosaurus is theropod dinosaur.J. Spencer (talk)23:10, 3 February 2009 (UTC)[reply]

Any reference why is it classified along with Sinraptorids?--92.118.191.48 (talk)15:52, 29 March 2009 (UTC)[reply]

If the reason you believe this is because of its spines, they were barely visible on a living animal and it would have looked similar to Allosaurus or Megalosaurus.— Precedingunsigned comment added by24.36.148.242 (talk)22:23, 27 October 2011 (UTC)[reply]
