Morphospace occupation of archosauromorphs. a Two-dimensional morphospace of all Early (grey dashed line with white pentagons, silhouette marked with asterisk) and Middle Triassic non-archosaurian archosauromorphs (grey solid line with grey pentagons) and pseudosuchians (black solid line with grey circles). b Two-dimensional morphospace of Late Triassic archosauromorphs showing the morphospace of non-archosaurian archosauromorphs (grey solid line with grey pentagons) and crown archosaurs (black solid line) with pseudosuchians (without phytosaurs) (grey circles), phytosaurs (white squares), and ornithodirans (white circles). c Two-dimensional morphospace of all Early Jurassic archosaurs with ornithodirans (black dashed line with white circles) and pseudosuchians (black solid line with grey circles). Note that graphs show the morphospace of entire epochs and are not always equivalent to the time bins. All silhouettes taken from (www.phylopic.org)
