In other news, I delivered my PhD thesis on stegosaurs the other day😅☠

The Miragaia exhibit in Museu Geológico de Lisboa is finally opening next May!!

As an aperitif until then, here's one of the posters I made to compare, in a single plate, just some of the many differences between M. longicollum and Dacentrurus armatus that makes them different species!

My first paper of the year, "Dacentrurine Stegosaurs in North America: New Occurrences from the Upper Jurassic of USA (Morrison Formation)": doi.org/10.3390/d180...

You can also find here the best published photos of the material of Miragaia (=”Alcovasaurus”) longispinus that survived to this day.

PVC25 The many differences of the stegosaur Miragaia longicollum from Dacentrurus armatus YouTube video by BackBoneRock

youtu.be/HK2ftzlac34 if you have 15min and are still confused if Miragaia ever went away, our video-talk from PVC25 (www.palaeovc.org) explains it all.

TL;DR: the last authors to allege that M. longicollum could be the same as D. armatus omitted 17 of the previously found differences. So no.

FYI for anyone still in doubt, Miragaia never went away because the last authors to allege it to be synonymous with D. armatus only discussed 10 out of the 27 differences found between M. longicollum MG 4863 and the holotype of D. armatus. Find out more in our @palaeovc.bsky.social video! #Miragaia

For anyone that might have been confused for the past few months if Miragaia longicollum is a valid species or not, we have a video-talk right now in the Palaeontological Virtual Congress demonstrating how it differs from D. armatus - mostly reiterating what was already demonstrated in Costa & Mateus (2019), as the last authors that alleged that M. longicollum would be synonymous with D. armatus only discussed 10 out of the 27 characters found to differ M. longicollum MG 4863 from the holotype of D. armatus. This research differs the most from previous for being the first with first-hand comparisons of both NHMUK PV OR 46013 (the type specimen for Dacentrurinae) and MG 4863 (the most complete dacentrurine in the world), as well as with many other stegosaur type-specimens. In our presentation you can find many never-before-seen photos of both holotypes, MG 4863 and other specimens comparing these species. If you haven't registered yet, you still can for just 5€, and see ours and 350 other scientific presentations until March 25th!! https://www.palaeovc.org/ In our presentation you can find many never-before-seen photos of both holotypes, MG 4863 and other specimens comparing these species side.

Happy birthday to Sophie our Stegosaurus ⁦‪@NHM_London‬⁩ - 10 years to the day since she was unveiled to the public! 🎂🎂🎂

Miragaia longicollum MG 4863 "Miragaia Project" is now on YT! YouTube video by BackBoneRock

The Miragaia Project is now on Youtube too! Plenty more videos ready to come soon!

The Miragaia Project is on BlueSky too!
And to start off, here's something from almost a year ago, when we did a preview of the project in Aljustrel (Alentejo, PT), neeearly ready but with a few parts unfinished, so focused on the making-of.
You can expect the final exhibit in MG early next year 🙂
