Information about this site and figures?

I’m not necessarily trying to find the figures, just know the brand and years of production/where they were sold? I’m looking specifically at the section labeled “Extinction Animal Figures”, which is a set I’ve never seen or heard of before. Are there other unknown sets on this site? I see Kaiyodo, Colorata, Yowie, Bandai, and probably more. Please let me know if anyone knows anything!

That website has been a reference for some us for many years. It looks to be the records of a personal collection, but instead of taking original pics, they just posted the promo pics. He/she hasn't updated with any figures for a long time, but have updated with some coins and stamps (the author seems to collect mainly insect stamps and coins).

I refer to it often, but there are a few errors here and there, mainly I think cut-and-paste errors.
