Hey! Those are my dinosaurs!
The same ones, they are Chinese toys, sold in this country by an outfit called Ja-Ru in New Jersey.
I used to have a really nice set when I was a kid, very accurate reproductions, but smaller than the Ja-Ru set, and without the speculative but plausible paint jobs. I even had a little diorama set up with a pond, and trees, etc where I displayed them in realistic, ecological poses.
I was such a nerdy kid I even had them segegrated by epoch. I had Jurassic, Triassic and Cretaceous communities and would swap them around every few days.
