Lavocatia

Lavocatia is an extinct mammal genus of the Lower Cretaceous from Spain. It was a member of the also extinct order of Multituberculata, and lived alongside of dinosaurs. Like most Mesozoic mammals, it was a shrewish-sized critter.
(For the technically minded, suborder "Plagiaulacida", family Pinheirodontidae.)

Genus: Lavocatia Canudo JI & Cuenca G, 1996

Species: Lavocatia alfambrensis Canudo JI & Cuenca G, 1996
Place: Galve
Country: Spain
Age: Barremian, Lower Cretaceous
Remarks: This genus is apparently differentiated by the number of cusps on the tooth; 15, if my non-existent knowledge of Spanish can be trusted.
Also referred to in the reference is Peramura. This was a more 'advanced' group of mammals, possibly ancestral to ourselves, (see Peramus[?]).
