LP-4450-IEI is an indeterminate and unnamed genus of enantiornithes that lived in Spain during the Cretaceous.
Description[]
The remains were studied in December 2006, focusing on histology. Unknown in other enantiornithes, LP-4450-IEI may possess a squamosal bone. This enantiornithe is a juvenile from El Montsec Formation. It had a humerus that has pores that travel obliquely through the cortical. The bone surface is rough on the distal end of the humerus. Short longitudinal traits are observed at the epiphysis.
