Macronaria indet.

(Figs 24 Y-AA; 25A)

DESCRIPTION

In addition to the turiasaur, a second sauropod taxon may be present at Angeac-Charente site. It is only represented by a single abraded tooth and a tooth recovered from microremains (Figs 24 Y-AA; 25A). They are spatulate and characterized by straight and subparallel distal and mesial edges at the base of the crown, and by the presence of a convex labial and concave lingual surface. Based on these features, these teeth are assigned to a macronarian sauropod probably close to Camarasaurus (Wilson 2002; Upchurch et al. 2004; Mocho et al. 2017).

Sauropod track casts have also been recorded at Angeac-Charente. Thay are represented by casts of pes and manus footprints (Rozada et al. 2021). In 2018, a sauropod footprint cast was observed above and in contact with an in-situ broken sauropod radius. It represents a spectacular “instantaneous” preservation of the action of a sauropod pes or manus crushing a sauropod long bone, and inducing bone modifications (breakage, displacement and reorientation) and sediment deformations (Rozada et al. 2021). The footprints are identified as Sauropoda indet. because of the general circular morphology of the pes, the characteristic tubular metacarpal arrangement of the manus and also the huge size of the prints (Carrano & Wilson 2001; Wilson 2005).
