Genus Phatthalungoceras Tongtherm & Nabhitabhata, 2018

Diagnosis: Trematoceratid with depressed cross section, short chambers and expanded siphuncular segments.

Type species: Phatthalungoceras srisuki Tongtherm & Nabhitabhata, 2018

Included species: Only the type species.

Remarks: The only known specimen was first described as Tienoceras sp. A in Tongtherm et al. (2016) and later established as new species and genus by Tongtherm and Nabhitabhata (2018). However, the holotype is relatively poorly preserved, and judging by the illustrations, it is possible that the reported depressed cross section is a result of compaction or erosion. If this is the case, the genus is essentially identical with Pseudotemperoceras due to its short chambers and expanded siphuncular segments.

Occurrence: Thailand; Middle Triassic (Anisian).
