Jubbulpuria
Encyclopedia
Jubbulpuria is the name given to a dubious
genus
of small dinosaur
from the Late Cretaceous
of India
.
The genus was in 1932 named by Friedrich von Huene
. The generic name refers to Jabalpur in the vicinity of which the fossils were found. The type species
, Jubbulpuria tenuis, was described by von Huene and Charles Alfred Matley
in 1933. The specific name means "slender" in Latin
.
Its fossil specimens were found by Matley in the Lameta Formation
, dating from the Maastrichtian
. They consist of two syntype
s, GSI K27/614 and GSI K20/612, each being a partial distal caudal vertebra. A third distal tail vertebra, GSI K27/599, has been referred to the species.
Jubbulpuria was a small predator, estimated to have been 0.5 meters high, 1.2 meters long, and weighing a few kilograms.
Jubbulpuria was originally classified by von Huene as a coelurid dinosaur similar to but smaller than Coeluroides
, another poorly known theropod from the Lameta Formation. Recent researchers have concluded that its position is hard to determine with any certainty beyond a general Theropoda
incertae sedis
and that it should be considered a nomen dubium
. It may have been a ceratosaur.

Type species
In biological nomenclature, a type species is both a concept and a practical system which is used in the classification and nomenclature of animals and plants. The value of a "type species" lies in the fact that it makes clear what is meant by a particular genus name. A type species is the species...
