Critterzoology<p>My parasitologist friend (who is on Bluesky @the-episiarch.bsky.social) told me about a parasitic flatworm that left its fossilized hooks on Lodeacanthus gaujicus and Asterolepis ornata from the Devonian of Latvia, and was described by Ieva Upeniece in 2001.</p><p><a href="https://ecoevo.social/tags/parasitology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>parasitology</span></a> <a href="https://ecoevo.social/tags/parasites" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>parasites</span></a> <a href="https://ecoevo.social/tags/flatworm" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>flatworm</span></a> <a href="https://ecoevo.social/tags/fossil" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fossil</span></a> <a href="https://ecoevo.social/tags/palaeontology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>palaeontology</span></a> <a href="https://ecoevo.social/tags/invertebratepalaeontology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>invertebratepalaeontology</span></a> <a href="https://ecoevo.social/tags/invertebrates" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>invertebrates</span></a> <a href="https://ecoevo.social/tags/sciart" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sciart</span></a> <a href="https://ecoevo.social/tags/scientificillustration" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>scientificillustration</span></a> <a href="https://ecoevo.social/tags/devonian" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>devonian</span></a> <a href="https://ecoevo.social/tags/palaeozoic" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>palaeozoic</span></a> <a href="https://ecoevo.social/tags/marinelife" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>marinelife</span></a> <a href="https://ecoevo.social/tags/prehistoric" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>prehistoric</span></a> <a href="https://ecoevo.social/tags/placoderm" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>placoderm</span></a></p>
Critterzoology<p>A Dunkleosteus, reconstructed with extensive facial soft tissue, about to bite into an ammonite.
