Time travel portal with ancient debris/ bone blocks

Time travel to see a new mob dinosaurs. Craft new weapons (e.g. swords, spears) with dinosaur teeth or claws to craft swords which do the same amount of damage as a gold sword but more durable. Travel the new dimension in search for dinosaur eggs to be able to hatch and have you own dinosaur tamed. You could also make it slightly realistic by putting the old blocks and their graphics in the dimension. Some dinosaurs could be hostile like the T-Rex and the velociraptor and some neutral dinos like the brontosaurus. You could also feed the neutral dinos for them to allow you to ride them. The way to craft the portal could be like the nether portal but with bone blocks or ancient debris.
