Sadly, the holotype specimen was destroyed after the museum, where the fossils were displayed at, was destroyed by Allied forces during the night of 24/25 April 1944. Newer discoveries from Tunisia in 1999 and Morocco in 2005 and 2014 suggest that Spinosaurus may have reached 15 metres (49 ft) in length. A size estimate by Dr. Dal Sasso suggests that the animal could have reached a length of 18 metres (59 ft) in length, however this claim may be an over-estimation.
