The dinosaur's life began in the humble egg, exactly like birds of today. Coincidence? I don't think so. It is amazing to think all the birds flying around this park are descendants of dinosaurs, Study of fossil evidence makes this the accepted theory.
If upon death of a dinosaur and they were "lucky" enough to be buried in mud, sand or volcanic ash, they got to be fossilized! Bad news for them, but good news for the people to came along much later and got to study them or just appreciate that such great creatures once ruled our planet.
Can you name the owner of the skull enclosed in the cache?
