Further material is known for _Megaraptor_, including nice forelimb

You may be thinking of _Ultrasaurus tabriensis_, which was based on an
alleged ulna (actually, a partial humerus). The dimensions of this sauropod
were overstated due to misinterpretation of the material.
No, most of that leg was hypothetical. It was based on a dorsal vertebra
(belonging to Supersaurus) and a referred scapulocoracoid (belonging to
Yes, and thus _Ultrasaurus macintoshi_ is a junior synonym of _Supersaurus
vivianae_. (I heard a rumor recently that there is a move to sink _S.
vivianae_ into the genus _Barosaurus_ - is this true?)
