The tachash — its hides covered the Mishkan, and Yechezkel shoes Yerushalayim in its leather. Its status is the Gemara's and is not in doubt: only the hide of a tahor animal was fit for the work of heaven, so the tachash was tahor. What it WAS the same sugya leaves open — a creature of its own kind, one horn in its forehead, which the Sages ruled neither beast nor wild animal, provided for the hour and hidden after; the badger, the dolphin, a fine dyed leather. Tachash the son of Nachor is a different entry, on the names lists.
