My wife has this on a shirt.
I remember this book, I don’t remember microdosing, but I’m pretty sure the dinosaur hatched from a chicken egg.
Was it Dinotopia? https://jamesgurney.com/products/life-lessons-from-dinosaurs-preorder
Not sure about OP, but it reminds me of The Enormous Egg.
That book looks so familiar.
I know this guy from Dinotopia series.
Was it his pet?
I think it started out that way but eventually they took the dinosaur to a museum because they couldn’t do it on their own. It was a children’s book I probably read 30 years ago.
A museum has many dinosaurs he can play with. That’s so cute that he gets to live with his relatives, all the other living… waiting something is wrong, something is very wrong…
NOOOO!!! DON’T GO THERE!!! ISN’T A TRAP!!!
There was a book like that, but this illustration is from a calendar James Gurney did.
Legend took a prehistoric dose
