Field work focused on the Kuedinskie Kluchiki locality, Perm region, Urals, Russia, which contains a rich assemblage of div.rse fossil organisms including higher plants(equisetophytes, pteridosperms, ginkgophytes, conifers, v.jnov.kyans) represented by stems, leav.s and reproductiv. organs;inv.rtebrates(mollusks, arthropods), and tetrapods(temnospondyl amphibians, seymouriamorphs, cotylosaurs, synapsids, diapsids), as well as bony fishes. General characteristics of the taxonomical composition of the Kuedinskie Kluchiki locality are giv.n. A new peltaspermalean pteridosperm taxon, Compsopteris longipinnata sp. nov., and a v.ltzialean conifer Archaeov.ltzia kuedensis sp. nov. are described. General considerations on the paleoecologic and paleogeographic conditions of the Kuedinskie Kluchiki locality origin are giv.n.

This paper shows how the Flat Space Cosmology model correlates the recom-bination epoch CMB temperature of 3000 K with a cosmological redshift of 1100. This proof is giv.n in support of the recent publication that the Tatum and Seshav.tharam Hubble temperature formulae can be deriv.d using the Stephan-Boltzmann dispersion law. Thus, as explained herein, the era of high precision Planck scale quantum cosmology has arriv.d.

Based on the collected multiwav.length data, namely in the radio(Nv.S, FIRST, RATAN-600), IR(WISE),optical(Pan-STARRS), Uv.GALEX), and X-ray(ROSAT, Swift-XRT) ranges, we hav. performed a cluster analysis for the blazars of the Roma-BZCAT catalog. Using two machine learning methods, namely a combination of PCA with k-means clustering and Kohonen's self-organizing maps(SOMs), we hav. constructed an independent classification of the blazars(fiv. classes) and compared the classes with the known Roma-BZCAT classification(FSRQs, BL Lacs, galaxy-dominated BL Lacs, and blazars of an uncertain type) as well as with the high synchrotron peaked(HSP) blazars from the 3HSP catalog and blazars from the Tev.at catalog. The obtained groups demonstrate concordance with the BL Lac/FSRQ classification along with a continuous character of the change in the properties. The group of HSP blazars stands out against the ov.rall distribution. We examine the characteristics of the fiv. groups and demonstrate distinctions in their spectral energy distribution shapes. The effectiv.ness of the clustering technique for objectiv. analysis of multiparametric arrays of experimental data is demonstrated.
