Abstract

To nye fossile papegøjer fra det nedre eocæne 'Moler' (Fur Formationen) i Danmark (c. 54 mio. år) beskrives. Et unavngivent stykke placeres i den uddøde familie af stamgruppe papegøjer, Pseudasturidae (slægt og art incertae sedis), mens en anden (Mopsitta tanta ny slægt og art) er den størst kendte fossile papegøje til dato. Begge stykker er de første beskrevne fossiler af deres art fra Danmark. Selvom Mopsitta fylogenetiske position er uklar (den klassificeres som familien incertae sedis), er den tættere på nulevende Psittacidae end til nogle andre kendte palæogene papegøjer og kan derfor repræsentere den ældst kendte kronegruppe papegøje. Udgivelsesdato: 15. maj Two new fossil psittaciform birds from the Lower Eocene ‘Mo Clay' (Fur Formation) of Denmark (c. 54 Ma) are described. An unnamed specimen is assigned to the extinct avian family of stem-group parrots, Pseudasturidae (genus and species incertae sedis), while a second (Mopsitta tanta gen. et sp. nov.) is the largest fossil parrot yet known. Both specimens are the first fossil records of these birds from Denmark. Although the phylogenetic position of Mopsitta is unclear (it is classified as family incertae sedis), this form is phylogenetically closer to Recent Psittacidae than to other known Palaeogene psittaciforms and may, therefore, represent the oldest known crowngroup parrot.
