🌈 Dr Ross Brooks<p>I had an enlightening time being shown behind the scenes at London's Natural History Museum today. Huge thanks to the brilliant Josh Luke Davis, science writer at NHM, and to Alessandro Giusti, senior curator of Lepidoptera, for showing me the Museum's collection of gynandromorph butterflies. Wow! 🦋💜🦋 </p><p>I made sure to say hi to Chas . . .</p><p><a href="https://mastodon.social/tags/NHMLondon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NHMLondon</span></a> <a href="https://mastodon.social/tags/museum" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>museum</span></a> <a href="https://mastodon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://mastodon.social/tags/biology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>biology</span></a> <a href="https://mastodon.social/tags/zoology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>zoology</span></a> <a href="https://mastodon.social/tags/naturalhistory" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>naturalhistory</span></a> <a href="https://mastodon.social/tags/animals" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>animals</span></a> <a href="https://mastodon.social/tags/butterflies" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>butterflies</span></a> <a href="https://mastodon.social/tags/Darwin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Darwin</span></a> <a href="https://mastodon.social/tags/gynandromorph" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>gynandromorph</span></a> <a href="https://mastodon.social/tags/queer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>queer</span></a> <a href="https://mastodon.social/tags/lgbtq" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lgbtq</span></a> <a href="https://mastodon.social/tags/QueerInSTEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>QueerInSTEM</span></a></p>
Jonathan T<p>If you've ever wondered just how big a Megalodon shark tooth is, here's your answer. </p><p>For comparison, a great white shark tooth would be around the size of the person's thumb.</p><p>The Latin binomial for the species, Otodus megalodon, literally means "big tooth" you will not be surprised to read.</p><p>Just how big these sharks grew is a matter for debate but 'huge' is one way of looking at it. Not as ridiculously big as in the terrible Meg films, though. </p><p>Taken at <a href="https://mastodon.me.uk/tags/NHMLondon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NHMLondon</span></a>, Jan 2016.</p><p><a href="https://mastodon.me.uk/tags/FossilFriday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FossilFriday</span></a></p>
Jonathan T<p>I knew I had my own photos... I was privileged enough to take these at a special event many years ago at the <a href="https://mastodon.me.uk/tags/NHMLondon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NHMLondon</span></a>: this is the real deal, the fossilised lower jaw of a Mastodon americanus - not a cast - purchased in 1844 and originally excavated in Missouri, USA. The teeth are what give Mastodon its name - mastos from breast and odous from tooth - and, no, I'm still not seeing the resemblance to breasts. Look closely and the teeth in this fossil are fantastically opalescent. <a href="https://mastodon.me.uk/tags/FossilFriday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FossilFriday</span></a></p>
Jonathan T<p>This is a reproduction of one of my earliest <a href="https://mastodon.me.uk/tags/FossilFriday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FossilFriday</span></a> posts on this platform (foolishly, I let them all auto-delete). It's the Missouri Leviathan. Aka the American Mastodon. </p><p>Now housed in the central hall of <a href="https://mastodon.me.uk/tags/NHMLondon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NHMLondon</span></a>, this fossil was unearthed as part of a 'graveyard' of <a href="https://mastodon.me.uk/tags/Mastodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mastodon</span></a> fossils by Albert Koch in 1840. </p><p>It's fair to say that Koch, being a showman interested in making money, took some liberties with his reconstruction of the fossilised animals he had found...</p><p>(1/5)</p>

Jonathan TI'll confess I know practically nothing about my <a href="https://pixelfed.social/discover/tags/FossilFriday?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#FossilFriday</a> for today, but it's one of my favourites at the <a href="https://pixelfed.social/discover/tags/NHMLondon?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#NHMLondon</a>, solely because of the quality of the preservation of the whole animal as seen in this close up (of what I assume is a high-quality cast). <br> <br> The label is potentially inaccurate because it's in the Fossil Marine Reptiles gallery, and I don't think they've been updated in there for decades:<br> <br> Marine crocodile<br> Mystriosaurus bollensis<br> 187-178 million years old<br> Lower Jurassic.
