Eoconstrictor is an extinct genus of booid snake, which supposedly had infrared vision, from the Eocene of Germany (Messel Pit). The type species, E. fischeri is known from multiple well-preserved specimens found in the Messel Pit of Germany. It was originally named as Palaeopython fischeri by Stephan Schaal in 2004,[1] but examination of the genus showed that it represented a distinct lineage; it was renamed as the new genus Eoconstrictor in 2020.[2] In a subsequent study Georgalis, Rabi & Smith (2021) reinterpreted "Paleryx" spinifer from the Eocene Geiseltal Lagerstätte (Saxony-Anhalt, Germany) as the second species species belonging to the genus Eoconstrictor.[3] Palci et al. (2023) named the third species belonging to this genus, E. barnesi described on the basis of fossils from the Geiseltal Lagerstätte.[4]
