Sources

Every fact on dinosaurs.im links to the page it was checked against. This is the full list.

All sources were checked on 24 Oct 2026. Each fact was matched word for word against the source text before the site was built, and any that didn’t match were cut.

We avoid figures that change over time. Where a figure can change (sizes, which are estimates and vary between studies, and the dates of geological periods, which geologists refine), its link reads “[source · checked 24 Oct 2026]” so you know exactly when we looked.

Spotted a mistake? Tell us and we’ll fix it.
