@DrNathanLujan Not spines from the same specimen at least. The ones in the specimen are where one would expect, check the last couple seconds of the video. It could be an Ariid.

Catfishophiles...check out this apparently complete Eocene fossil, presumably siluroid. Curious what the bilateral paired structures are at the end. Part of the Weberian apparatus? Medially displaced, thickened pectoral spines?

I still prefer the Brownian motion version, second entry in my blog post. Feliz navidad, @phytools_liam! gaballench.com/2018/12/15/mer…

An oldie from #phytools blog, but the code still works: a phylogenetic Christmas tree in R. You could say it's a real "Yule" phylogeny. (Get it?) With credit to @gaballench. blog.phytools.org/2018/12/a-phyl…
