need help with re-release pet dates

[imp.]

hi! i'm really sorry if this is the wrong place to post this. i need help figuring out which of my pets are re-releases (like dec. 18th) and what their original dates are

rares - accounts/viewgroup.php?groupid=8127737&userid=628446
very rares - accounts/viewgroup.php?groupid=8127738&userid=628446
extremely rares - accounts/viewgroup.php?groupid=8127739&userid=628446
omg so rares - accounts/viewgroup.php?groupid=8127740&userid=628446

i have them sorted by rarity but i haven't played in so long, i don't remember which are re-releases :')
