The skull of Spinosaurus isn't known from complete remains. However, it is estimated to be 1.75 meters, or 5.7 feet, in length.
Spinosaurus do not live like crocodiles but have a crocodile like skull.
Spinosaurus is not known from complete skeletons. The size estimates I am aware of say that Spinosaurus was about 49 feet long. I doubt that they grew to be as long as 66 feet.
About 14-17m long and 10 tonnes.Answer:There is some ongoing discussion on this. Initial estimates were 6 tons in weight and 15 meters (49 ft) in length. Some studies postulated a lower mass. More recent estimates are that Spinosaurus was 16 to 18 metres (52 to 59 ft) long and 7 to 9 tonnes (7.7 to 9.9 short tons) in weight
The Spinosaurus could lay 3-5 eggs at a time

Estimates place Spinosaurus at 49 feet long and weighing at least 4.4 to 10 tons. Giganotosaurus was 43 feet long and probably weighed between 6.5 and 13.8 tons. Thus, Spinosaurus was definitely longer, but either may have been heavier.
Spinosaurus is estimated to have been 49 feet long and weigh 4.4 to 10 tons or more. Megalodon was at least 50 feet long and thus would have weighed over 53 tons. Thus, Megalodon was much heavier than Spinosaurus but was only slightly longer.
Yes, Spiosaurus had 1 natural enemy. It's name was Carcharodontosaurus. Note that note many bones of Carcharodontosaurus have been found. But from estimates it was close to the size of T-rex. It's skull has been found; and it was about 5 feet long! So when you compare this to a smaller scale preadator like Spinosaurus{12-14 feet tall, 39-40 feet long} Spinosaurus has a very small chance at living.
