The bone preservation is poor, but the skin of this specimen nicknamed \u201cHelge\u201d is excellently displayed. These details are due to the special preservation in hot volcanic ash, which literally burned the poor animal into its cemented grave. There were certainly also larger animals in this lush forest, but their flight instinct got them out of the danger zone in time, at least outside the later excavation area. <em>Ascendonanus<\/em>, in contrast, was the victim of its own adaptations: It is the oldest vertebrate known so far with extensive adaptations to a life in the treetops. As such, it probably preferred to flee upwards, towards the boiling hot ash rain. Five such animals were found in just a few square meters.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Stipple drawing of the \u2018climbing dwarf\u2019 Ascendonanus from the Chemnitz Petrified Forest, with preserved skin.<\/p>\n","protected":false},"author":1,"featured_media":3577,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"pn_jahr":"","pn_taxon":"Ascendonanus nestleri; Varanopidae","pn_auftraggeber":"Museum f\u00fcr Naturkunde Chemnitz","pn_ausstellung":"","pn_masse":"","pn_quelle_url":"https:\/\/doi.org\/10.1007\/s12542-018-0405-9","pn_lizenz":"\u00a9 Palaeonavix","pn_alt_url":"https:\/\/www.palaeonavix.org\/index.php\/scientific-documentary\/ascendonanus","pn_mitwirkende":"","footnotes":""},"portfolio_category":[161],"portfolio_skills":[],"portfolio_tags":[],"class_list":["post-3579","avada_portfolio","type-avada_portfolio","status-publish","format-standard","has-post-thumbnail","hentry","portfolio_category-scientific-documentary"],"acf":{"pn_jahr":"","pn_taxon":"Ascendonanus nestleri; Varanopidae","pn_auftraggeber":"Museum f\u00fcr Naturkunde Chemnitz","pn_ausstellung":"","pn_masse":"","pn_quelle_url":"https:\/\/doi.org\/10.1007\/s12542-018-0405-9","pn_lizenz":"\u00a9 Palaeonavix","pn_mitwirkende":"","pn_verwandte":"","pn_links":[{"bezeichnung":"Museum f\u00fcr Naturkunde Chemnitz","url":"https:\/\/www.naturkundemuseum-chemnitz.de\/"}],"pn_publikationen":[{"zitat":"Spindler, F., Werneburg, R., Schneider, J.W., Luthardt, L., Annacker, V., & R\u00f6\u00dfler, R (2018): First arboreal \u2018pelycosaurs\u2019 (Synapsida: Varanopidae) from the early Permian Chemnitz Fossil Lagerst\u00e4tte, SE Germany, with a review of varanopid phylogeny.
