Di-cephalic conjoined twins among reptiles are well known to occur and survive (perhaps more so that in other species). Di-cephalic human conjoined twins are also well known. A cluster of a dozen conjoined twins were documented to have been born in Rivne oblast, Ukraine, a zone impacted by chronic ionizing radiation from the Chornobyl (Chernobyl in Russian). Theological disputes weather conjoined twins have one or two souls are of no interest in biology, what is known is that the personalities of conjoined identical twins can be quite different.
