I'm always astounded at these discoveries that sat in a drawer or storage for decades before someone finally noticed what they were. I don't know why, but I always expect science to be better organized than that. If I could go back in time, I'd make it a project to get universities to inventory all their collections, catalog the identifying details, and publish these catalogs once a year in a journal dedicated to this purpose. Or at least once a decade.

[@ScumfuckMcDoucheface]

Oh man, I think that's actually a fantastic idea... Kinda sketchy though too right It's almost like you're tempting the burglars and thieves haha =) It would definitely get these phenomenal collections to be better researched and studied obviously.... just think of the untold treasures just waiting to be rediscovered in the dusty crypts under the world's great museums =) man oh man oh man, what I'd give to have a few hours to go explore the R.O.M.'s collections in Toronto

[@rickkwitkoski1976]

@Cat Woods do you know of the Burgess Shale fossil collection? Richard McConnell of the Geological Survey of Canada first discovered this. His finds were explored by paleontologist Charles Doolittle Walcott in 1907. From these the idea of the "Cambrian Explosion" was developed. So MANY phyla of animals began "suddenly" (geologically speaking). Trays and trays of unexplored fossils sat in hiding. Several years later people began a closer inspection of them and realized that so many had not had ANY description or an attempt at classification. One fellow one declared, "Not ANOTHER F@@KING Phylum!" However, in more recent years, these have been re-examined and the number of phyla has been reduced significantly as paleontologists realized that they were doing way too much splitting. What you suggest is fine... but WHO is going to do it? It is not FREE to do these things. People do need to be paid just so that they can live. Where is that money going to come from? Tax payers money? You will get a LOT of pushback by very influential people who see no advantage in doing what you suggest. Especially those who deny the results of scientific discovery... while at the same time reaping the technological benefits of the discoveries.

[@Cat_Woods]

@@rickkwitkoski1976 I didn't know that about the Burgess Shale fossils. I said I would do it if I could go back in time before the internet, and I meant I'd make it my life mission. Which is obviously false, because if time travel turned out to be possible, there's a lot more that would need to be figured out (maybe all the fossils would turn out to be planted by me in my time machine 🙂). I hope I'm right to assume that the internet enables better sharing than in the days when fossils were shoved in drawers and forgotten about.

[@medea27]

Keep in mind that your average museum or university has tens of thousands of fossils (prepared & not-yet-prepared) and a very limited number of people, work hours & budget to study them. Some digs will yield hundreds of individual bones that need to be properly prepared before studying, and if you've only got the budget to work on, say, a new therapod then anything else goes into storage because you just don't have the resources. It then tends to get left to your least experienced (and unpaid!) students or volunteers to inventory what's not being worked on, and they do their best to correctly ID everything... many of these 'discoveries' are simply misclassified or unidentified specimens that need a specialised eye to pick out. I spent several weekends helping our mammalogy professor inventory hundreds of individual teeth from a dig, the largest being half the size of your little fingernail. We're talking hundreds of inventory items labelled virtually the same thing, and so damn tiny that you'd need to look at each one under a microscope to identify it. It was certainly an experience!

[@ThePalaeontologist]

The rapid radiation of relatively basal (by Dinosaurian standards) aka 'primitive' Herrerasaurids could have something to do with the Carnian Pluvial Event/Episode (or Carnian Humid Event/Episode) from ~234-232 Ma. They are already rather beautifully advanced in form as compared to numerous other Archosaurs from the Triassic Period, even as far back as 233 Ma. Which is to say, they were already looking pretty developed even by the mid Carnian Age. However, there had been a considerable propensity for a long time in Palaeontology, for many creatures we'd now consider to be related Archosaurian Dinosauromorphs, rather than true Dinosaurs, to be simply referred to as Dinosaurs. This continued to cause confusion as in reality, no true Dinosaurs were definitively known from before about 225 million years ago, that is, until the likes of Herrerasaurus and Eoraptor came to light. Now we know the Dinosaurs were at least 233 million years old, and likely a few million years at least, older than that. There are more recently claims of South African and Malagasy (Madagascan) fossils to stretch back into the Ladinian Age, and some even claiming Anisian. Which in other words, means Dinosaurs over 240-245 Ma. Which, I do not adhere to. This seems dubious in my view, as I'd argue true Dinosaurs likely did evolve from Dinosauromorph Archosauromorph Archosaurs, around the early Carnian Age (although I am not going to reject the idea of a Ladinian Age true Dinosaur, it would not necessarily have enough of the diagnostic characteristics of a true Dinosaur, and more likely demonstrate another transition fossil species on the way to something more like a true Dinosaur) For an example of this matter, the Dinosauromorph known as Saltopus, was long considered to be a Dinosaur in many books for years, until it was gradually realised to be slightly too primitive to fit the diagnostic description of one, anatomically. In a sense, what is attempted in the pursuit of the earliest Dinosaurs, in a taphonomically fraught fossil record, is the search for 'Dinosaur Zero'. And good luck with that; because finding the exact earliest origin point of Dinosaurs, is of course going to be tough. Necessarily, it will be borderline so primitive by Dinosaurian standards, as so to be scarcely discernible from out of a myriad of closely related Dinosauromorph kin and likely direct progenitors. When and where this happened isn't exactly known, though can be inferred quite reasonably to the Carnian Age in general, though with potential Ladinian Age origins. That said, we have a strong idea that it may have been more likely Dinosaurs evolved first in what was then Southern (or maybe even more accurately South-Western) Pangaea. Geographical boundaries would have slowed Dinosaur radiation into the Northern Hemisphere as well as there being a range of well-established Archosaurs and Therapsids already there (not to mention various other reptiles and the more ancient Temnospondyl Amphibians) Yes, all of these also lived in the South, though conditions at places like Santa Maria and Ischigualasto (i.e. Carnian Triassic Brazil and Argentina, in Southern Pangaea) were very conducive to the rise of the early Dinosaurs, for whichever reasons. The significance of the Carnian Pluvial Episode, is that it saw heavier precipitation, and humidity, allowing for plentiful wetland and monsoonal like river systems with sweltering conditions under the Triassic Sun and the Carnian thunder. They were well-watered with abundant river channels and wetlands, giving a very different look to the often considered completely barren Triassic, than has often been realised. It has been more well-understood since the matter came into scientific debate from 1989 onward, and although there is still some dispute on how things happened in more depth, the Carnian Pluvial Episode is still generally considered an important aspect of the potential acceleration of Dinosaur evolution. Dinosaurs were more water efficient to begin with, and had their classic physical advantage of walking with their limbs aligned beneath their bodies and not in a less energy efficient sprawling gait. During the Carnian, the conditions were very rainy and this may well have made places like Santa Maria, a perfect testbed for the then new Dinosaurs to flourish. Speculatively one might argue that some Dinosaurs had their first starts in places where Dinosaurs could be even more important palaeoecologically. Conditions were still generally hot and dry across the Triassic, with conditions getting much drier again in the Norian Age, though it is possible the Carnian Pluvial Episode helped them in their early days.
