Extended Data Fig. 2: Selected specimens of Mirasaura grauvogeli preserving integumentary appendages.
From: Triassic diapsid shows early diversification of skin appendages in reptiles
a, SMNS 97304, an isolated appendage preserving the proximal portion. b, SMNS 97333, an isolated appendage preserving the proximal portion. c, SMNS 97280, a largely complete crest. d, SMNS 97338, an impression of a largely complete crest lacking the proximal region. e, SMNS 97281, a bundle of four integumentary appendages. f, SMNS 97337, a bundle of around seven integumentary appendages. g, SMNS 97300, an isolated appendage preserving the distal portion. h, SMNS 97286, two overlapping integumentary appendages preserving the distal portion. i, SMNS 97342, two overlapping integumentary appendages preserving the distal portion. Black boxes indicate regions of variation in ruga morphology, highlighting the malleability of the rugae in the appendages. Scale bars, 5 mm (a, f, h), 10 mm (b, e, g, i), 50 mm (c), 20 mm (d).
