hauyn888 Posted August 24, 2017 Share Posted August 24, 2017 Found this "cutted" fish years ago, it slept in a box in my barn, now I´ve prepared it but can´t imagine what had happened million years ago, the fossil is complete articulated but cutted! See the pictures from Positiv and Negative ( The Negative Para.1 I had coloured - the PosPara. 2 is the Original not coloured). Who has an explanation what happened?

ynot Posted August 24, 2017 Share Posted August 24, 2017 As the rock was being pushed up to the surface it cracked and there was some displacement along the fractures. The pieces will be very fragile along the cracks. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 24, 2017 Share Posted August 24, 2017 A cool reminder of the huge geologic forces at play. Happy hunting, Mason Link to comment Share on other sites More sharing options...
hauyn888 Posted August 24, 2017 Author Share Posted August 24, 2017 Hello ynot, I had a similar consideration, but on closer examination of the overall situation, the fund situation, this reasoning is not plausible. 20 cm further, 50, 30 in layers above and below this foundation layer no more "cuts" are dived - all fossils are there in situ and "perfect" .... and now? ... well, I am only 55 Years old, so still have time to find the solution ... I like this fossil because it is perfect, perfectly broken! Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 24, 2017 Share Posted August 24, 2017 Faulting will often cause fossils to slide apart like that.

For unknown reasons some layers will be more brittle than other layers and will fracture and slide while an other layer close by will bend and stretch.

FossilDudeCO Posted August 25, 2017 Share Posted August 25, 2017 We see this sometimes in the Green River Formation. I will find a perfect half on the edge of a crack only to find the next side blank. This is a neat find in which both sides of the fracture so preservation.

caldigger Posted August 25, 2017 Share Posted August 25, 2017 It happens to be one of those very little known German "Zig-Zag" fish. Oooo, very rare indeed! Link to comment Share on other sites More sharing options...
