A new primitive alligatorine from the Eocene of Thailand: relevance of Asiatic members to the radiation of the group

Abstract: Despite the report of fragmentary remains from China, the fossil record of primitive Alligatorinae is unbalanced with most of its members reported from North America and Europe. Here, we describe cranial, mandibular, and some postcranial elements of a new alligatorine taxon from the Late Eocene of Krabi Basin, southern Thailand. Krabisuchus siamogallicus gen. et sp. nov. was a small animal probably not surpassing 2 m in total length. Despite deformation, the remains show a dorsally elevated cranium similar to … Show more

“…Although the Thai species Krabisuchus siamogallicus was recovered by Martin & Lauprasert (2010) as an alligatorine, and the unnamed specimen from the Maoming Basin of Guangdong Province, China was recovered by Skutschas et al (2014) as an alligatorid of unresolved affinities, the three named Chinese extinct alligatoroid species have never been included in any cladistic analysis. Determining their phylogenetic positions would represent a significant step towards understanding alligatoroid evolution on a global scale.…”

“…Specifically, five new taxa were added to the matrix: Asiatosuchus nanlingensis and Protoalligator huiningensis were added to explore their phylogenetic positions (Young, 1964(Young, , 1982; Krabisuchus siamogallicus and an unnamed alligatorine (the "Maoming specimen") were added, based on codings from previously published matrices (Martin and Lauprasert, 2010;Skutschas et al, 2014), to evaluate the phylogenetic relationships among Asian alligatoroids; and finally, "Eoalligator chunyii" was added as a separate OTU to test its possible synonymy with A. nanlingensis.…”
