A type specimen of the palaeodictyopterid Dunbaria fasciipennis FOSSIL  INSECTS -

Last Updated: 2 January 2011  Please do not use any of the images of fossil insects on these pages without permission.

Paleodictyoptera:Spilapteridae: Dunbaria fasciipennis Tillyard in Dunbar & Tillyard 1924.  This insect, with its beautifully-patterned wings and long cerci (the "tails"), had a wingspan of about 37 mm.  It flew some 260 million years or so ago over what are today the prairies of central Kansas.  This image is a scan of the original glass plate negative used for the type description of the species.  Scan courtesy of and used with the permission of the Cawthron Institute, Nelson, New Zealand, which is where Robin J. Tillyard, one of the great insect paleontologists and entomologists, worked when he studied the Yale collection of Kansas Elmo fossils.  Thanks to Rod Asher of The Cawthron Institute for scanning the images for me.

KANSAS & OKLAHOMA FOSSIL INSECT SITES:

This site will focus on the Permian fossil insect Lagerstätten of Kansas and Oklahoma (The Wellington Formation sites - see map on right):

But there are other fossil localities representing other geological eras at which insect fossils have been found (though not in the numbers and varieties found at the Wellington sites):

megveins.jpg (207212 bytes)This picture is from an Excel spreadsheet  in which I am digitizing the geometry of the hind wing of Megatypus schucherti.  These data are from a scaled scanned image of the fossil.  I am now adding to this information the depth dimension so that I will have three-dimensional geometry of the wing veins and will be able to estimate the cross sectional moment of inertia of the wing and therefore its bending stiffness.   Hopefully this will allow, by comparison with similar parameters for extant Odonata, some inferences about the flight of this giant Permian insect.   Vein nomenclature follows Riek and Kukalova -Peck (1984).  Information ©2002 by Roy J.
