Campanian extinctions

Sphecomyrminae is an extinct subfamily of ants in family Formicidae known from a series of Cretaceous fossils found in North America, Europe, and Asia. Sphecomyrminae contains eight genera, divided into two tribes Sphecomyrmini and Zigrasimeciini. The tribe Sphecomyrmini contains the six genera Armania, Cretomyrma, Gerontoformica, Orapia, Pseudarmania and Sphecomyrma; while Zigrasimeciini contains Boltonimecia and Zigrasimecia. A number of taxa have been removed from the subfamily and placed either in other subfamilies or are now treated as incertae sedis in Formicidae.

Dolichosauridae (from Latin, dolichos = "long" and Greek sauros= lizard) is a family of Cretaceous aquatic lizards. They are widely considered to be the earliest and most primitive members of Mosasauria, though some researchers have recovered them as more closely related to snakes.
