[1] After enduring constantly changing line-ups and problems with distribution, promotion, and even ownership of the rights to the second album, Thanatos folded in 1992, the final straw being the cancellation of a tour with Cannibal Corpse and Exhorder.

After a few shows in Greece and a short tour with Pungent Stench, the band recorded their fourth album, Undead.

[2] Release of a fifth album, Justified Genocide, was postponed when the band's label at the time, Black Lotus Records, went bankrupt; Dan Swano finished the mix for the CD.

[3] To celebrate more than twenty years of Dutch death metal, Thanatos released (on Chinese label AreaDeath Productions) a limited-edition box containing Emerging From The Netherworlds, Realm Of Ecstasy, and Angelic Encounters, besides 56 bonus tracks and 19 videos.

In 2019, Thanatos celebrated their 35th anniversary with a double-CD compilation album, a 7 inch vinyl EP and a special show in their hometown Rotterdam featuring a lot of former band members.
