Palaeotodus emryi Olson

This is just a doodle, or sketch of a Palaeotodus emryi, a rather large tody ancestor from the Early Oligocene of Wyoming, USA.

This fossil tody was nearly 50% larger, and probably had a somewhat shorter bill and larger wings than the recent species.


Today, todies are restricted to the Caribbean, where five species, which all more or less look the same, are found on Cuba, on Hispaniola as well as on Jamaica and Puerto Rico.

It is very strange to see how little these birds have changed during the last 30 Ma. years of their known existence!


FMNH PA789 again

This is now the semi-final version, it just needs to be colored.

The twig is from an undescribed plant species from the same fossil bed where the bird was found, it has the number FMNH PP54658, whatever that means, however, it seems to have been a deciduous species at least.   🙂


This is a small bird from the Eocene of Wyoming, USA, it was only about 10 cm long and is so far known from a complete skeleton with most of the feathers preserved as well.

The bird is not yet described but is apparently currently under study, it may turn out to be related to Morsoravis sedilis Bertelli, Lindow, Dyke & Chiappe, and to belong into a new family, probably named the Morsorornithidae or alike, which then again are perhaps somehow related to the mousebird/parrot/songbird ‘orbit’.

The reconstruction shows it while somewhat stretching its left wing, it was ‘fun’ to draw all this wing feathers, and I probably will do that NEVER EVER AGAIN!!!   😉

I found this book mentioned by Darren Naish on his “Tetrapod Zoology” blog and thougt it to be a ‘must have’ for me, since it was said to cover all of the fossil bird species found so far in the Green River Formation.

It actually does! (Well, at least I think it does.)

The book probably describes all of the known invertebrates, vertebrates and plants found so far in the Eocene Green River Formation, Wyoming / USA, and the photos are indeed brilliant!


I can only recommend this book for everyone interested in the Eocene era.   🙂
