and only species is A. velauciensis.Discovery and naming
Between 2009 and 2010, excavations were carried out at the
More specimens, including an occipital condyle (MMS/VBN.09.41), a right portion of the braincase (MMS/VBN.09.167) and a probable left pterygoid (MMS/VBN.09.158a), were described by Díez Díaz et al. (2018),[4] and a few parts of the skull, several teeth, vertebrae from each section of the vertebral column, ribs, chevrons, shoulder and pelvic girdle elements, most of the bones of the arm, and most of the bones of the leg are also known from multiple individuals, including VBN.93.MHNA.99.21.[3][4]
Etymology
The
Classification
A 2018 cladistic analysis of Titanosauria places Ampelosaurus, Atsinganosaurus, and Lirainosaurus in the new lithostrotian clade Lirainosaurinae. Díez Díaz et al. (2018) suggested that adults reached 8–12 metres (26–39 ft) long, possibly up to 14 metres (46 ft) long for the largest individuals, and a body mass of 3.5–5 metric tons (3.9–5.5 short tons),[4] while Díez Díaz et al. (2021) reportedly corrected the estimates to 5.38–8.95 metres (17.7–29.4 ft) and 2.46–5.26 metric tons (2.71–5.80 short tons).[3]
