of theropod dinosaur

, India
. It lived 183 - 175 million years ago in the Toarcian
, Early Jurassic
. It is currently classified as Neoceratosauria incertae sedis
but may in fact be a ceratosaurid or basal
tetanuran.
The type species, D. indicus, was named by Yadagiri in 1982. Little is known about the genus, as the only fossil evidence is a partial pubis
- some paleontologists consider it to be a nomen dubium
