A modern dragonfly specimen (Libellulidae: Libellula subornata) posed
next to a specimen of a forewing of one of the smallest Protodonata, Paralogidae:
Oligotypus tillyardi. The fossil is from Noble County, Oklahoma,
and was collected in July 2003 by Michael Montgomery of Wichita State
University. It is in my collection, which will ultimately reside at the
Johnston Geology Museum at Emporia State University, Emporia, Kansas.

Another photo of the specimen of Plathemis subornata, this time placed on
a fossil specimen of Megatypidae: Typus readi. This is specimen
number FI-40105, from the American Museum of Natural History, New York, which I
have had on loan to the Johnston Geology Museum for study. Compare the
corrugated venation of the two wings.

A specimen of a female Libellulidae: Perithemis tenera placed on the Tupus
readi forewing fossil. This picture shows more of the fossil wing.
