A very snappy bird with strange trousers – Cruralispennia multidonta Wang et al.

This tiny thing could be called the „Cretaceous Nicobar Pigeon“, it had somewhat elongated neck feathers, the typical short tail, or rather a not-a-tail-at-all tail so typical for many of those strange Cretaceous enantiornithine birds that we now already know.

The strange-feathered creature comes from China, where it lived some 130 Million years ago in the late Early Cretaceous.

The genus name refers to its crural feathers (bird trousers) which are actually found in many birds, but here they are shaped like nothing ever seen before, maybe like a thin sheet of ceratin with a chewed end, or brush-like end, not at all like a feather. The species name again refers to its multi-toothed beak.


a sketch of which I hope that I can produce a painting from some day ….

The bird reached a size of about 10 to maybe 11 or 12 cm when fully grown. The body feathers appear to have been more hair- than feather-like, and they may have been dark, while those on its neck were somewhat elongated and apparently were even glossy [1] … why not. 


Unfortunatly I could not find any plant species from the same place and time.
