legionary zodiacal animal standards: evidence?

[ursinius]

Avete People,

I am looking for the sources on the use of animal standards in the imperial roman army other than the aquila: there figures a ram standard (identifying LEGIO I MINERVIA) at Trajans column, but that is the only clear source I could find...

Could it be that this type of standard was also a type of the "Imago"?

Some of the books just state that "some legions may have used also standards with zodiacal signs" or something like that.

But what are the sources ?

Thanks in advance,

sebastiaan,
