Hybrider Wohlfahrtskorporatismusfore are serially dependent upon some single, ultimate cause with clocklike behavior. This hypothesis is controversal, in part because of questions regarding the identity and timing of certain extinction events and because of speculations concerning possible catastrophic extraterrestrial forcing mecObliterate 发表于 2025-3-23 17:56:16

Anagenetic characteristics, such as loss of bithecae and reduction of first order stipes (progressive atrophies from quadriradiate, through triradiate to biradiate organizational schemes) are achieved polyphyleticalepicardium 发表于 2025-3-24 00:49:16

The biologic evolution is characterized by successive decreases in diversity during the Frasnian followed by successive increases in diversity during the Famennian. The result was replacement of the Frasnian brachiopod-bryozoan-tentaculitid -trilobite -crinoidal faunalMAL 发表于 2025-3-24 14:25:15
Hybrider Wohlfahrtskorporatismushanisms. New data on extinctions of marine animal genera are presented that display a high degree of periodicity in the Mesozoic and Cenozoic as well as a suggestion of nonstationary periodicity in the late Paleozoic. However, no periodicity is evident among the as yet poorly documented extinction events of the early and middle Paleozoic.lesion 发表于 2025-3-24 15:00:34
