Camel cataphracts?

[MeinPanzer]

I have never heard of camel cataphracts. Not Parthian nor otherwise.

Herodian IV.14.3 - Nisibis, AD 217:

"Meanwhile Artabanus was upon them with his vast and powerful army
composed of many cavalry and an enormous number of archers and
cataphracts who fought on camels, jabbing with long spears.

15.2-3:

"The barbarians caused heavy casualties with their rain of arrows and
with the long spears of the kataphraktoi on horses and camels, as the
wounded the Romans with downward thrusts. But the Romans had easily
the better of those who came to close-quarters fighting. And when the
size of the cavalry andthe numbers of the camels began to cause them
troublem they pretended to retreat and then threw down caltrops and
other iron devices with sharp spikes sticking out of them. They were
fatal to the cavalry and the camel-riders as they lay hidden in the
sand, not seen by them. The horses and the camels trod on them and fell
onto their knees and were lamed, throwing the riders off their backs.
As long as the eastern barbarians are riding on horses or camels they
fight bravely; if they dismount or are thrown they are easily taken
prisoner because they do not resist in close-quarters fighting. And
further, they are hindered from running away by the loose fodls of their clothes hanging around their legs."
