The Bullyland Diatryma is a well done replica of an athletic, robust bird. Bullyland scores with a credible posture, nice colouring and some neat details. On the other hand one can say Bullyland perhaps interpreted Diatryma a little bit too clumsy.
Diatryma, nowadays better known under the name Gastornis, is an extinct genus of large flightless bird that lived during the late Paleocene and Eocene periods of the Cenozoic.
