TqB Posted July 14, 2018 Share Posted July 14, 2018 Megaonychites, form genus for the giant hooks that some belemnites have been shown to carry as a pair. By analogy with modern coleoids, they were probably carried by the males and used as mating claspers. This is a fairly large one at 3.4cm (the range is 0.5cm to about 4cm). It most likely belonged to a large Acrocoelites trisulculosus, by far the most common belemnite in these beds. Very rare in the UK but more frequent in the equivalent Holzmaden Posidonienschiefer. I've only seen one other from here - a partial - and that was mine until I gave it away thinking at the time it was a fish bone. (It was a long time ago... ). A recent acquisition from the usual auction site. (Found by a knowledgeable friend so the stratigraphy is good.) Mulgrave Formation ("Jet Rock"), Toarcian Stage, Lower Jurassic, near Whitby, Yorkshire, UK. 6 Tarquin Link to comment Share on other sites More sharing options...

Miocene_Mason Posted July 14, 2018 Share Posted July 14, 2018 Very interesting. Great find 36 minutes ago, TqB said: gave it away thinking at the time it was a fish bone. (It was a long time ago... ). We’ve all had those moments. I left a weird looking black thing in a Silurian rock a year ago, only to learn it was a Rare shark tooth four months later “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

TqB Posted July 14, 2018 Author Share Posted July 14, 2018 Thanks, all! @doushantuo - Huxley was famously taken in by an arm crown from one of those (or similar) that someone had cobbled onto a belemnite rostrum. Of course, Holzmaden has the real thing with Passaloteuthis and Acrocoelites as well as other coleoids. Sadly, no belemnite arms are known from Yorkshire yet...
