osaurs were first reported from the Indian subcontinent in the late 1800s, =

m central, western, and southern parts of India and from central western Pa=

Here we report on three titanosaur vertebrae representing regions of the sk=

 resolution of their affinities is precluded by their incompleteness and th=
at of titanosaur vertebral columns in general, lack of coding of character =
data for titanosaur presacral and anterior caudal vertebrae, and relatively=
 coarse understanding of the evolutionary relationships of titanosaurs. Com=
parisons with contemporaneous and spatially proximal titanosaurs from Indo-=
Pakistan, Madagascar, and South America provide insights into their affinit=
ies. The dorsal vertebrae share close affinity with Isisaurus from India an=

 anterior caudal vertebra, which shares characteristics with Tengrisaurus f=
