A new giant python from the Pliocene Bluff Downs Local Fauna of northeastern Queensland

Abstract
Liasis dubudingala n. sp., described on the basis of isolated vertebrae from the Early Pliocene Bluff Downs Local Fauna, is the largest snake known from Australia. Dependance of vertebral proportions on intracolumnar position indicates that the fossil taxon can be excluded from the Morelia/Python clade. High neural spines suggest possible affinity with Liasis olivacea, whereas a posterior dentary fragment with small teeth is unlike L. olivacea and more similar to Liasis mackloti or species of Bothrochilus and Leiopython. As these extant species have all recently been treated as members of Liasis, the new species is assigned to that genus.
