As of July 2022 the World Spider Catalog has accepted the following 3 species: [4] Theraphosa apophysis Tinter, 1991 - Colombia, Venezuela and Brazil; Theraphosa blondi Latreille, 1804 - Venezuela, Brazil and Guyana Theraphosa stirmi Rudloff & Weinmann, 2010 - Guyana and Brazil One species has been changed to the genus Sericopelma.
The Minoan eruption had four phases. Phase 1 was a white to pink pumice fallout with dispersal axis trending ESE. The deposit has a maximum thickness of 6 m and ash flow layers are interbedded at the top. Phase 2 has ash and lapilli beds that are cross stratified with mega-ripples and dune-like structures. The deposit thicknesses vary from 10 ...
In 1992, Coffin and Eldholm initially defined the term "large igneous province" as representing a variety of mafic igneous provinces with areal extent greater than 100,000 km 2 that represented "massive crustal emplacements of predominantly mafic (magnesium- and iron-rich) extrusive and intrusive rock, and originated via processes other than 'normal' seafloor spreading."
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity, the production, intrusion and extrusion of magma or lava. Volcanism is the surface expression of magmatism.
Particularly, a transpressional fault that cuts through layers is related to the transportation and ascent of magma by creating space for emplacement. [19] Shape of different magma emplacement structures: (a)sill, (b) pluton, (c) laccolith and (d) lopolith. [4] Sills are tabular sheet intrusions. Plutons are large, thick tabular bodies.

The species was first described by Andreas Tinter in 1991, as Pseudotheraphosa apophysis. [1] Tinter purchased an individual under the name "Pamphobeteus exsul", but realized that it could not be correctly named, as it possessed stridulatory organs.
