Abstract

There were 17 mass extinctions include 15 mass extinctions of Sepkoski JJ, and other two extinctions such as: Dresbachian extinction events which were from 502 Mys ago, taxonomic loss of mass extinctions: 90% and “Aptian extinction” was from 113 to 117 Mys ago.

15 mass extinctions (85%) have a period of 250 million years with limilt the error rate is about ±5%.

two extinctions did not have the period:

1) Cenomanian-Tithonian from 94 Mys ago, taxonomic loss : 15%,

2) Eocene-oilgocene transition from 34 Mys ago, taxonomic loss : 11%.

11 mass extinctions (65%) in four points (with limilt the error rate is about ±5%)of the cycle of 250 million years.

In “A” point:

1) Dresbachian extinction from 502 Mys ago, taxonomic loss : 90%,

2) End-Guadaluoian (Capitanian) from 260 Mys ago, taxonomic loss : 47%,

3) end-Permian–Triassic extinction from 252 Mys ago, taxonomic loss : 58%.

In “B” point:

1) Taghanic event was from 384 Mys ago, taxonomic loss : 30%,

2) The late Devonian/kellwasser from 375 to 360 Mys ago, taxonomic loss : 35%.

3)“Aptian extinction” from 113 to 117 Mys ago.

In “C” point:

1)end- Cretaceous (masstrichtian) extinction from 66 Mys ago, taxonomic loss : 39%.

2)Serpukhovian extinction from 330 to 325 Mys ago, taxonomic loss : 23%.

In “D” point:

1) Lau event from 424 Mys ago, taxonomic loss : 23%,

2) Pliensbachian- Toarcian from 186 Mys ago, taxonomic loss : 14%.

3)end Triassic–Jurassic extinction from 201.3 Mys ago, taxonomic loss : 37%.

The preriod relates to resonances of Milky Way Galaxy both of general matter and dark matter.
