Dino History World exists because the best dinosaur information online is scattered across a dozen outdated sites, and none of them treat paleontology like the living, ongoing science it is. This is one place to actually browse it — real taxonomy data, real museum photography, real news, and a design that doesn’t look like it was built in 2009.
It’s for the curious kid who wants to know what a Spinosaurus actually ate, the parent looking something up mid-argument at the dinner table, the aspiring paleontologist scoping out university programs, and the collector trying to tell a real fossil from a fake one. Same site, different doors in.
The goal is to keep building this out — more genera fully documented, more museums mapped, more of the culture and commerce around fossils covered honestly — for as long as people find it useful. If that’s you, sharing it with someone who’d also like it is genuinely how this grows; there’s no ad budget behind this, just the site itself.
