coming soon another new Ediacaran taxon from Newfoundland. This one is an #Arboreomorph from the #Ediacaran of the NE Avalon Peninsula discovered and written up with PhD students Pascal Olschewski @simonrosse.bsky.social. The art needs some work to do justice to the fossil but Happy #FossilFriday!

unnamed elongate Arboreomorph frond with broad flat disc numerous small branches arise from a central axis at a high angle

reconstruction of an elongated frondose arboreomorph organism with an inferred upright mode of life. Depicted on a hypothetical deep marine seafloor with patchy white microbial communities

Our final #Ediacaran palaeontology paper of the year! Introducing #Aninoides coombsorum gen et sp nov Such a beautiful fossil. At the moment only known from our Inner Meadow site, Newfoundland. Paper led by PhD student Simon Rosse-Guillevic Not OA sadly :-( www.researchgate.net/publication/...

$three images of a leaf shaped fossil with low angle first order branches and fractal like higher order branches left is photo of a replica (mold of the lower surface) middle is interpretive drawing and right is a plan view of the inferred top of the same fossil$ photo of holotype of Aninoides coombsorum super mature specimen with long first order branches.
looks a bit like a comet below is interpretive drawing of the same.
disk is accidental not associated with the fossil itself
