The smallest biggest theropod dinosaur

Spinosaurus is the longest, and among the largest predatory dinosaurs. A tiny claw phalanx of the foot, discovered in Cretaceous-aged sandstones of the Sahara, shows a peculiar shape compatible with an early juvenile Spinosaurus. The fossil is from the smallest known individual of this giant, sail-backed theropod. The findings suggest the small specimen retains the same locomotor adaptations as the large version — such as traversing soft substrates or paddling — during the entire lifespan.
