ten feet, approximately
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.
The Spinosaurus could lay 3-5 eggs at a time
For 99.732 million years

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.
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.
about 2 inches long
Spinosaurus is known only from incomplete skeletal remains, so it is very difficult to estimate its weight. Guesses range from 4.4 tons to 10 tons or even as high as 18 tons. Spinosaurus was probably about 49 feet long.
There were many different species of raptors, and larger ones had larger sickle claws. Velociraptor was 6 feet long and had a claw that was 2.6 inches long on the outside edge. Utahraptor was 23 feet long and had a claw that was 9.4 inches long.
