Brachydectes is an extinct genus of lysorophian tetrapods that lived from the Late Carboniferous to the Early Permian. It had a very small head and long body, B. elongatus had 1–2 centimetres (0.39–0.79 in) long skull (averagely 1.4 centimetres (0.55 in)) and pre-sacral length up to 150 centimetres (59 in) (averagely 45 centimetres (18 in)),[2][3] while B. newberryi, which have proportionally larger skull than B. elongatus, for specimen with 7.6 millimetres (0.30 in) skull roof had estimated total length of 11 centimetres (4.3 in), while the largest skull exceeds 3 centimetres (1.2 in).[1][3]
