Strangely enough, Lydekker (1887) recognized that the _Titanosaurus_
caudals were very similar to those of _Macrurosaurus_.  But although
Lydekker was certain that _Titanosaurus_ was a dinosaur closely allied
to _Cetiosaurus_ and _Pelorosaurus_, he wasn't convinced that
_Macrurosaurus_ was actually a dinosaur!

Huene is the guilty party.  He made a dog's breakfast of the Lameta
sauropod remains from Bara Simla.  His reasons for erecting
_Antarctosaurus septentrionalis_ were certainly misguided, and still
haunt us today.
