 In their original description , Krause and colleagues suggested that Lavanify was most closely related to the then @-@ unnamed Indian sudamericid . They based this proposed relationship on the shared presence of prominent , continuous bands of IPM . The teams who named the Indian gondwanathere in 2007 both agreed with this proposed relationship . In their description of Dakshina , Wilson and colleagues added the presence of an infundibulum and of perikymata to the evidence for the relationship between the two . These three characters are synapomorphies ( shared derived traits ) for the Bharattherium @-@ Lavanify clade . They also share the presence of furrows on the lingual side of the teeth only , but whether this is a derived feature is uncertain . Wilson and colleagues list two autapomorphies ( unique derived traits ) of Lavanify : presence of a V @-@ shaped dentine island and absence of enamel on one side of the crown . Prasad and colleagues who named Bharattherium , noted the absence of enamel on part of the crown of a Bharattherium tooth and interpreted this trait as a synapomorphy of Bharattherium and Lavanify . They also mentioned the presence of a furrow and infundibulum as shared traits .
