Harrison C.J.O. (1982) A new tiny raptor from the Lower Eocene of England. ARDEA 70 (1): 77-80

geen Nederlandse samenvatting beschikbaar op internet The foot of a small bird from the Lower London Clay, Division A, of the Lower Eocene of England, comprises the distal end of a tarsometatarsus with some phalanges. It is identified as that of a raptor, probably a tiny falcon, Parvulivenator watteli gen. et sp. nov. It appears to have been about three-quarters to two-thirds the size of the smallest known bird of prey, the Black-thighed Falconet Microhierax fringillarius. It lacks any medial displacement of the outer flange for the trochlea for the second digit, and the phalanges indicate proportionally longer and narrower toes than in Recent species.
