Mineral CupThe gap is closing in the battle of limpet teeth vs shiny gem!But <a href="https://mastodon.social/tags/Goethite" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Goethite</a> still needs to gather just over 40 votes in just under 20 minutes if it wants to beat out <a href="https://mastodon.social/tags/Topaz" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Topaz</a> to compete in <a href="https://mastodon.social/tags/MinCup23" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MinCup23</a> next round.

InoruOkay, so looks like neither is very chaotic this round - <a href="https://blorbo.social/tags/topaz" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#topaz</a> is primarily used for pretty-shinies (and do we blame them? No), and <a href="https://blorbo.social/tags/goethite" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#goethite</a> is *bog iron*, y'all.However! I'm voting goethite and lemme tell you why: 1) it has a cool habit of coming in after other minerals and taking over where they were, crystal shape and all! (Okay a lot of opportunistic minerals do this, but I think it's cool every time.) (I've got more reasons, hang on, hitting char limit.) <a href="https://blorbo.social/tags/MinCup23" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MinCup23</a>

Cormacs CoastLimpet (Patella sp.) feeding trails - the one in the centre was clearly eating on the go! It's trail reminds me of a bungee rope. Limpet teeth are made up of fibers of Goethite - one of the strongest known natural substances.
