Trained as a geologist in the 1980's we prepared for field works in Spain at the museum of Natural History in Leiden, NL. In Spain there would be Silurian outcrops so we were told to look for graptolites. What kind of animal was it, we asked. The answer: "we have no idea". Knowledge has emancipated the graptolites.

Technically, plenty of people (who study graptolites) thought it was solved in the 1940's, but there were some hold-outs who disagreed for a long time.

​@@antoniohorta5656 Multituberculates are usually classified as crown group mammals, i.e. those groups descended from the last common ancestor of all living mammal groups (granted that's not as high of a bar to fill as you might think due to monotremes being a thing but still), and are actually usually placed closer to Theria (so marsupials and placental mammals) than to the monotremes (platypuses and the like). So they're true mammals, as opposed to more basal synapsis like the cynodonts.

I was a fan of paleontology as a child in the 80s and found fossils in the gravel fill between parking lots around my hometown. After all this time I finally learn what one was that always bugged me that I couldn't find it. 0:57 "B" looks almost exactly like what I couldn't identify back then. This is my first time hearing about graptolites and I'm really excited to finally know. :)

By studiing geology and paleontology in Czechia, you hear a lot about graptolites, but noone ever explained to us what type of animals they really were

Could we get a video on the evolution of the placenta/live birth and how it evolved convergently in both certain reptiles, amphibians and mammals? I've always been interested in how that came about but it's pretty hard to find information on (that doesn't require several years of study to understand 😅)

Trying to learn as much as possible about the Paleozoic Era. Fascinating underrated time. So much going on. This is really our origin story.

Eons is the perfect study break :D also, love the earrings! 😄

Thank you so much......the Silurian needs some love. Devonian as well.

I've either never heard of graptolites or only fleetingly until now, let alone had any idea they were so central to understanding all the drastic environmental changes that took place during the Silurian era that were hidden in plain sight for palaeontologists. There are so many weird things in Earth's prehistory I would never ever have heard of were it not for PBS Eons, and today I can add yet more to my list. By the way Michelle Barbosa Ramirez continues to be the world's best dressed palaeontologist, from the modern goth take on the 1920's/1930's vamp/flapper look to those cat skull earrings. How often do you see someone who makes their living educating people about weird extinct animals put this much work into having an instantly recogniseable fashion sensibility?

@@DavidBapst I truly wish he was! He was very involved with utilising graptolites to work out geological boundaries, temporally, as well as physically. He did a lot of research on the Burgess Shales, a continuation of which is in Wales. This was when 'continental drift' (Plate tectonics) was still young in science. Sadly he passed away some years ago from ALS-I could have really used his help on my dissertation lol. He was a wonderful, funny man and I miss him.

i have a suggestion for accessibility- it could be helpful for scientific terms to be said a bit more slowly and distinctly from the rest of the sentence. doesn't have to be a big change, but for people (like me) who don't use that terminology very often it can be hard to understand and contextualize sometimes. thanks for all the wonderful work y'all do!
