How long is a spinosaurus aegyptiacus?
Western Australian Museum gives Spinosaurus aegyptiacus an estimated upper length of roughly 15 meters. This restoration pairs that reference with the deeper tail supported by later fossil research.

A little more perspective
The museum’s Dinosaur Discovery account identifies aegyptiacus and lists an approximate 15-meter upper length. The source predates the later tail discoveries; its separate height is not reused here. The selected length remains an estimate from an incomplete and debated fossil record, not a complete measured skeleton.
The illustration incorporates the vertically deep tail documented in the 2020 research, while keeping the body extended along the length axis. Tail evidence informs the restoration independently of the older length reference. Exact soft tissues, sail outline and coloration remain uncertain; the modest skull crest distinguishes this depiction from the separately named mirabilis.
