A blurb about Paleofest 2019 is a bit overdue, considering it has now been over two weeks since the event. Of course, I have been rather busy and don't check DeviantART as often as I used to, but might as well make one now.
It was great to see
in person again! I'm hoping that I didn't miss any other deviantART users while I was there, but if you're there next year, you know what I look like. I still highly encourage anyone within the area or who doesn't mind paying for a bit to travel to go, though it has unfortunately gotten more expensive over the years.
Nonetheless, they were still many great talks. Thomas Holtz addressed why I hate drawing tyrannosaurs now (way too much heated debate on integument and lips that people on both sides take way too seriously), and how there still isn't anything conclusive to be said about
T. rex itself. Dr. Roy Plotnick also gave a fascinating lecture that instead focused on the future rather than the past. Dr. Plotnick talked about the Anthropocene and the fossil record it'll leave behind. Say some alien/human species visits Earth once we're all gone. Hopefully they'll love studying humans and livestock. Said future palaeontologists will be privileged perhaps with millions of cemeteries containing peoples of all ages and ethnicities. Livestock, especially cows, will be likely be the most prevalent fossil species on Earth after humans. Rather than seeing the biodiversity we see now, future palaeontologists of whatever species would be overwhelmed with humans, cows, chickens, dogs, cats, and several other livestock species. Elephants, tigers, Komodo dragons, etc, are all fascinating and charismatic beasts that may be extremely rare if not completely absent from the fossil record, given the chances of preservation. I believe zoos would be potentially interesting sites. Imagine if the world's only tiger fossil is known from a country such as China and then you find one in Kansas!
There are quite a few talks where information is embargoed, and I'm not inclined to spill secrets. Dr. Ashley Poust talked about "creodonts", the possibility of them being afrotheres, and how we're likely to see more taxonomic reworking of both mammals in general and "creodonts" in particular in the future. Aaron van der Eeest gave a lecture on tissue preservation in
Ornithomimus, Latenivenatrix, and
Chasmosaurus, whereas Denise F. Su discussed the palaeoecology of early hominins. Chasmosaurine histology was focused on by Carrie Levitt-Bussian, and I for some reason drew a
Centrosaurus in my notes. Alexandria Brannick talked about remains of
Alphadon from Egg Mountain, and how they may help to redefine marsupial phylogeny. James C. Lamsdell made an excellent case for using eurypterids as case studies for evolution, as we have a fairly robust phylogeny (with practically the same results under Bayesian inference and parsimony) that details the rise of eurypterids to apex predator status, their split into saltwater and freshwater forms, a trend towards increasing body size, and even the possibility of sexing sea scorpions (though we can't tell which is a male or a female, but we can infer sexual dimorphism). There's also some exciting adelophthalmid news that I believe is embargoed atm.
Jade Simon talked about
Anzu and how it grew, revealing some interesting embargoed information on Hell Creek oviraptorosaurs. Dan Lovelace gave a fascinating lecture on his work in the oft-ignored Popo Agie Formation, where he has been unearthing vertebrate remains for the last few years along with his children. There are several very exciting finds that I can't discuss. Sarah Gibson gave what was perhaps my favorite talk, even though I know little about prehistoric fish. This is where I learned about
Hemicalypterus, and she also talked about several other taxa she has worked on. This is also where I learned that there was a series of Triassic rift lakes similar to what we see in East Africa now, except these were formed between Morocco and the eastern seaboard of the USA. Armita Manafzadeh talked about reconstructing dinosaur locomotion by studying modern archosaurs, and how we both assume too little and too much of how dinosaurs could move. Eva Hoffman discussed
Kayentatherium, lecturing in detail on a Kayenta mom and her 38 babies. Clearly
Kayentatherium still employed a rather "reptilian" strategy of reproduction, and that big brains can often be associated with parental care and "cuteness" (with precocial young tending to look rather like miniature copies of their parents, as in
Kayentatherium). It may be inferred that parental care could've arose in some of the earliest mammaliaforms such as
Morganucodon. Maybe. Thomas Cullen talked about studies on Sue and on theropod growth, and that's about all I can say for now, but there is some interesting information that'll come out of the paper whenever it is published. Antoine Bercovicci and Regan E. Dunn both gave lectures on a botanical view of the K-Pg extinction event, and how we see a crash in plant diversity, followed by a huge spike in the number of ferns (ferns are excellent colonizers of ravaged lands, and were some of the first plants to grow in the areas affected by the eruption of Mt. St. Helens), and a relatively quick recovery of the forests of Hell Creek, which we may be restoring wrong. I believe that information may be secretive at the moment, so that's all I'll say as I loving infuriating tidbits.
Overall, I believe this was one of the most successful and interesting years of Paleofest with a great variety of lectures that were all given excellently. Even on topics such as Mesozoic fish and K-Pg pollen, I never found myself bored, though I was pretty tired on the first day. I can't wait to see what's in store for the future, and hopefully I may get to make more connections with the Internet palaeocommunity!
