[5] However, the recent discovery of S. lanciformis remains from the earliest Paleocene indicates that it just barely survived into the Cenozoic.

[5] The complete material from Jordan offered an extensive amount of valuable information about Saurocephalus.

[5] With an elongate, torpedo-like body, Saurocephalus was extremely fast and it was probably a formidable open-water ambush predator.

[13] S. lanciformis fossils are known from the early Danian of the Hornerstown Formation in New Jersey, indicating that they at least briefly survived the Cretaceous-Paleogene extinction event.

They appear to have persisted longer into the Danian than other Mesozoic fish that have their youngest records from the formation (Pseudocorax, Ischyodus, Anomoeodus, and Enchodus).
