The two spinosauruses were also 3D printed, at slightly different sizes. These spinosauruses are much larger than the ones in our world. The assumption is that they had an extra 65 million years in which to grow and adapt to a mostly marine existance. The yellow markings were applied by brush using Vallejo acrylic paint. The swimming dinosaurs were given a slightly glossy finish to reflect that they are constantly wet from periodically diving below the surface of the sea.
