supratendinal bridge
"Ossified bridge over a tendon; Particularly, the bridge over the extensor canal at the distal end of the tibiotarsus of certain birds. The presence of the bridge and the position of the canal opening relative to the condyles may have phylogenetic significance. Ericson (1997). http://palaeos.com/vertebrates/glossary/glossarySq.html."
