October halls of horror and Terror Birds. The strike of Paleopsilopterus

Paleopsilopterus is one of the smallest and by far earliest of the group with fossils dating back as far as sixty million years ago.‭ ‬In a world that had seen the disappearance of the dinosaurs under five million years before its existence,‭ ‬Paleopsilopterus thrived and was likely the form that would go onto to produce a greater diversification of terror birds including giants such as Kelenken and Brontornis.‭
