Some 55 million years ago, during a period called the Palaeocene-Eocene thermal maximum, the average temperature increased by 13 degrees over 10,000 years.

The last time the world experienced temperature rises of this magnitude was 55 million years ago, after the so-called Palaeocene-Eocene Thermal Maximum event.

Previous research into this period, called the Palaeocene-Eocene Thermal Maximum, or PETM, estimates the planet's surface temperature blasted upwards by between five and nine degrees Celsius (nine and 16.2 degrees Fahrenheit) in just a few thousand years.

Nearly 65% is part of the Palaeocene and Pleistocene Solimões Formation, a very extensive sedimentary deposit composed of table uplands which form barriers to the drainage.

Other formations within the Park include the older Palaeocene Prosperança and Trombetas formations, which underlie 17% and 8% of the Park respectively.

The most controversial of these ‘Mesozoic survivors’ is a diminutive and enigmatic animal from Upper Palaeocene North America: Chronoperates paradoxus, described by Fox et al. (1992) for a partial mandible and some isolated teeth from the Paskapoo Formation of Alberta.

Technical details of the molar cusps and roots, and the tooth count, better match those of dryolestoids more than docodonts, and in fact Reigitherium appears particularly closely related to the Palaeocene dryolestoid Peligrotherium, with both being united by Rougier et al. (2003) in the dryolestoid clade Reigitheriidae.

Alvarenga & Höfling (2003) grouped phorusrhacids into five subgroups; the small, gracile psilopterines, known from the Palaeocene to the Pliocene and including the oldest of all phorusrhacids; the mid-sized, shallow-skulled, gracile-legged mesembriornithines of the Miocene-Pliocene; the mid-sized patagornithines of the Oligocene, Miocene and Pliocene; the gigantic, robust brontornithines of the Oligocene and Miocene; and the mostly large, gracile-legged phorusrhacines of the Miocene, Pliocene and Pleistocene.
