Manticocerasman Posted October 9, 2018 Share Posted October 9, 2018 Although the most pieces of my collection are goniatites, I am more than happy to add other Devonian cephalopods to my collection from time to time. On my last field trip for devonian cephalopods I splitted a few nodules and some of them had a few uncommon fossils in them: Bactrites I rarely find decent fragments of them, but those few were looking promising. Bactrites, although they look like an orthocone are in fact straight Ammonoids and not a Nautiloid. the septas start to be slightly ondulated, but most important they have a ventral siphuncle, a typical trait of an Ammonoid. the first nodule had a fragment sticking out, and when I split the nodule another one was found inside. I kept both parts of the nodule and prepped the one inside and on top After prepping them I found out that neither of those were complete, but the were decent in size and well preserved. The second nodule on the other hand hand was much better, a piece of the Bactrites was sticking out from both ends of the nodule, so I new I had a complete specimen. The prepping was relatively hard as different parts of the cone had different forms of preservation, but in the end I got the whole specimen out of the matrix and is my best Bactrites until now. enjoythe pictures: 1st nodule with the specimen inside: after prepp: After prep with the top of the nodule containing an other fragment. prepp on the 2nd nodule: after prepp, with the different kinds of preservation visible: and the whole lot: growing old is mandatory but growing up is optional.

The Amateur Paleontologist Posted October 9, 2018 Share Posted October 9, 2018 Very neat fossils - love those Bactrites! Where did you find these specimens? -Christian Opalised fossils are the best: a wonderful mix between paleontology and mineralogy! Q. Where do dinosaurs study? A. At Khaan Academy!...

Heteromorph Posted October 9, 2018 Share Posted October 9, 2018 Nice Bactrites! Early cephalopod evolution is truly fascinating, especially when you can hold it in your hands! Link to comment Share on other sites More sharing options...
RJB Posted October 10, 2018 Share Posted October 10, 2018 I had to open up this post cause ive never even heard of 'Bactrites' before? Purty dang cool! Nice job Kevin. RB Link to comment Share on other sites More sharing options...
