My ds loves them. Besides legos we collect everything dino. We all love the Walking with Dinosaur series,and the related ones on insects and animals.
Ds just asked me this morning..."Do people who dig up dinosaur bones make a lot of money?" I may be wrong but I told him no they don't make a huge amount of money. I think they rely on grants to fund digs,so it can be touch and go.
I told him there are people who dig for dinosaurs as a hobby,and some have found stuff too. I told ds to do what he has a passion for.Whatever makes him happy everyday *to go to work*, and that happiness makes whatever money you get worth doing it.
