Manticocerasman Posted May 1, 2019 Share Posted May 1, 2019 I've been cleaning up a few boxes with devonian fossils from the past few months and came around this nice little fellow. I cleaned him up and gave him a paraloid treatment to preserve the pyrite. It is a complete specimen of a Bactrites sp. from the Matagne shales ( Frasnian, late Devonian ) from Belgium, both phragmocone and body chamber are preserved. They are a little unusual, as the do not belong to the nautiloids as his first appearance might suggest but they have their own subclass and are considered to be the ancestors of the ammonids ( they have a ventral syphuncle like all the ammonoids ) Fragments of them often pop up from the shales, but I rarely find them complete. This one is going in the display cabinets 5 2 growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...

Heteromorph Posted May 1, 2019 Share Posted May 1, 2019 Great example of an odd stage in cephalopod evolution. The pyrite preservation is stunning! Link to comment Share on other sites More sharing options...

Bringing Fossils to Life Posted January 16, 2022 Share Posted January 16, 2022 WOAH. I was just wondering, how can you tell Bactrites from Michelinceras if you can't see the siphuncle? I have some Bactrites from Pennsylvania, and what might be either a weathered Bactrites or Michelinoceras. Their septa are similarly spaced, so that doesn't help that much. I can't see the outer shell either, so I can't check for lirae. Can anyone help? Link to comment Share on other sites More sharing options...
