It is one of the most often told stories regarding the history of palaeontology: the long search for a convincing trackmaker, no longer assuming a large mammal or amphibian. In fact, <em>Chirotherium<\/em> was produced by larger Triassic pseudosuchians, a highly diverse group of archosaurian reptiles back then.<\/p>\n<p>Therefore, it nests among the stem group of all modern crocodiles, a clade in which the outermost toe of the foot is greatly reduced. On the evolutionary path towards this condition, chirotheres spread this fifth toe sideways and slightly backwards, in order to stabilise the narrow erect gait. So, what reminds us of a human thumb actually corresponds to the same position as our little toe.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Digital drawing of the Chirotherium trackmaker \u2013 and why the supposed thumb is actually the little toe.<\/p>\n","protected":false},"author":2,"featured_media":4623,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"portfolio_category":[160],"portfolio_skills":[],"portfolio_tags":[],"class_list":["post-3673","avada_portfolio","type-avada_portfolio","status-publish","format-standard","has-post-thumbnail","hentry","portfolio_category-sketchbook"],"acf":{"pn_news":false,"pn_jahr":"2026","pn_taxon":"Chirotherium; Pseudosuchia","pn_auftraggeber":"","pn_ausstellung":"","pn_masse":"","pn_quelle_url":"","pn_lizenz":"\u00a9 Palaeonavix \u00b7 Frederik Spindler","pn_mitwirkende":"","pn_verwandte":"","pn_links":null,"pn_publikationen":null,"pn_alt_url":"https:\/\/www.palaeonavix.org\/index.php\/sketchbook\/chirotherium-trackmaker","pn_highlight":true,"pn_produkte":null},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
