In a way, dinosaurs aren\u2019t just the source of the greatest excitement. When it comes to reconstruction, they\u2019re also the simplest and most convenient option. Some invertebrates, and echinoderms in particular, present a completely different challenge. Imagine you have to not only sketch a sea urchin, but truly capture its whole geometry, including its genus-specific characteristics and according to fossil data.<\/p>\n
In the end, not everything was needed, but the lessons learned were significant. It\u2019s inevitable that you\u2019ll keep hitting limits \u2013 in this case, not just those of 3D printability. After all, the spine-driven walking mode of the late Jurassic reef urchin Rhabdocidaris<\/em> is nicely concluded from the full arrangement.<\/p>\n","protected":false},"excerpt":{"rendered":" Construction drawing of Rhabdocidaris \u2013 why echinoderms are harder than dinosaurs.<\/p>\n","protected":false},"author":1,"featured_media":3698,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"pn_jahr":"2026","pn_taxon":"Rhabdocidaris","pn_auftraggeber":"","pn_ausstellung":"","pn_masse":"","pn_quelle_url":"","pn_lizenz":"\u00a9 Palaeonavix","pn_alt_url":"https:\/\/www.palaeonavix.org\/index.php\/sketchbook\/sea-urchin-blueprint","pn_mitwirkende":"","footnotes":""},"portfolio_category":[160],"portfolio_skills":[],"portfolio_tags":[],"class_list":["post-3700","avada_portfolio","type-avada_portfolio","status-publish","format-standard","has-post-thumbnail","hentry","portfolio_category-sketchbook"],"acf":{"pn_jahr":"2026","pn_taxon":"Rhabdocidaris","pn_auftraggeber":"","pn_ausstellung":"","pn_masse":"","pn_quelle_url":"","pn_lizenz":"\u00a9 Palaeonavix","pn_mitwirkende":"","pn_verwandte":[3741,3822],"pn_links":null,"pn_publikationen":null,"pn_alt_url":"https:\/\/www.palaeonavix.org\/index.php\/sketchbook\/sea-urchin-blueprint"},"_links":{"self":[{"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/avada_portfolio\/3700","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/avada_portfolio"}],"about":[{"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/types\/avada_portfolio"}],"author":[{"embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/comments?post=3700"}],"version-history":[{"count":1,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/avada_portfolio\/3700\/revisions"}],"predecessor-version":[{"id":4142,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/avada_portfolio\/3700\/revisions\/4142"}],"acf:post":[{"embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/avada_portfolio\/3822"},{"embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/avada_portfolio\/3741"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/media\/3698"}],"wp:attachment":[{"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/media?parent=3700"}],"wp:term":[{"taxonomy":"portfolio_category","embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/portfolio_category?post=3700"},{"taxonomy":"portfolio_skills","embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/portfolio_skills?post=3700"},{"taxonomy":"portfolio_tags","embeddable":true,"href":"https:\/\/www.palaeonavix.org\/en\/wp-json\/wp\/v2\/portfolio_tags?post=3700"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
