Extinct genus of ammonite
Eubaculites is an extinct genus of cephalopods in the family Baculitidae and each known species was initially placed within the related genus Baculites [ 1] [ 2] [ 3] until it was placed in a separate genus in 1926.[ 4]
Eubaculites existed from the Turonian until the Danian , and is one of the very last genus of ammonites , going extinct roughly 64.5 million years ago, which was around 500,000 years after the start of the Cenozoic . Specimens found in the Maastricht Formation in The Netherlands suggest that at least one species (E. carinatus ) survived the K-Pg mass extinction event , albeit being restricted to the Danian .[ 5] [ 6] [ 7] [ 8] [ 9]
