Another day, another (low-resolution) dinosaur cartoon. That's Arcocanthrosaurus (an even larger carnivore than T Rex), looking for dinner. Mama Rex is looking for him, however.
Although we don't have any eggs, it's thought that T-Rex eggs were only a bit larger than footballs (the beast is really only around 15 feet tall (my Alamosaurus is around the size of a 3 story office building. Trust me, T-Rex is dinky next to her.) The young grew very fast and more than tripled in size during the first year (if memory serves.)
I'll prep this one by boosting the resolution, sharpening it and deepening the colors, and adding a bit more sky to it.
