1. There are 6 main criteria for identifying lateral fold growth: 2. A lateral fold extends from the eye to the posterior portion of the tympanum. 3. Females possess a relatively shallow fur-lined pouch formed by lateral folds of skin. 4. The tail ends in a small caudal fin; there are no dorsal fins or lateral folds . 5. The skin of these frogs is smooth or finely granulate above, with a narrow glandular lateral fold . 6. Therefore, the progressive change in soil profile is more of a secondary evidence of lateral fold growth. 7. However, there was little evidence of a lateral fold -to-fin transition in the fossil record. 8. The lateral fin-fold theory hypothesized that paired fins developed from lateral folds along the body wall of the fish. 9. As former deflected streams, some of the wind gaps may show curvature that convex towards the direction of lateral fold growth. 10. The tail measures 86 & ndash; 90 % as long as the disc and has a flattened oval cross-section without lateral folds .
