This template's initial visibility currently defaults to collapsed, meaning that it is hidden apart from its title bar.
To change this template's initial visibility, the |state=parameter may be used:
{{Extinct squamates|state=expanded}} will show the template expanded, i.e. fully visible.
{{Extinct squamates|state=autocollapse}} will show the template autocollapsed, i.e. if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar, but if not, it is fully visible.
