I've never seen Deathsaurus IRL myself, but according to TFwiki:
"Deathsaurus's mold was originally a ten-changer, though the "gargoyle"/bat mode was neutered for this release due to the dropping of the bat snout piece, required to give his new head enough space inside his chest cavity for other modes. He still retains the other nine modes (robot, dragster, jet, two-headed dragon, hand, mammoth, hydrofoil, one-headed dragon, and winged griffin). His instructions, however, assign him the six modes of the original RID Megatron, including the gargoyle and omitting the boat, griffin, mammoth and flying dragon. His tail-piece was removed for in-box storage, but easily popped back on since it's on a ball-and-socket joint."
