Praepapilio,
a fossil genus Wikipedia |
| |
Praepapilio
is an extinct genus of swallowtail
butterfly from the middle Eocene
deposits of Colorado, United States,
comparable to the Lutetian epoch in age.
The genus is considered to be the only
representative of the fossil subfamily Praepapilioninae.
Praepapilio
is, so far, the only wholly extinct
subtaxon known within the swallowtail
family. Two species have been described,
each from a single fossil find. |

Praepapilio colorado
(Durden & Rose, 1978) Fossil from
Colorado |
| |
The holotype of P.
colorado, the type
species of the genus, is from the Middle Eocene-aged
Green River Shale, Parachute Creek
Member, near Raydome, Colorado. Durden
and Rose, in their 1978 paper, compare P.
colorado to the extant Baronia
brevicornis,
and suggest that P.
gracilis may be the same
species as P. colorado,
and that the differences between the two
are possibly due to sexual dimorphism. |

Praepapilio gracilis
(Durden & Rose, 1978) Fossil from
Colorado |
| |
As with P.
colorado, the holotype of
P. gracilis
was from the same site in Colorado. It
differs from the type species in being
smaller and more gracile in form, though
anatomical differences may be due to
sexual dimorphism. |

Evolution:
Sommerfugle har ikke de store fossiler.
De er frygtelig sarte skabninger, der
ikke er tilbøjelige til at bruge meget
tid omkring søer og vandhuller, som er
de steder, hvor de bedste fossiler er
bevaret. Larver er ligeledes vanskeligt
at fossilize fordi kun deres hoveder har
nok stof til at blive et fossil.
På grund af dette er det lidt svært at
se tilbage til oprindelsen af
sommerfuglen med kun omkring 50
sommerfugl fossiler i øjeblikket kendt
for videnskaben. Lad os se på, hvad der
er fundet, og hvad der er blevet
teoretiseret. |
