ITS TIME

FOR

DINOSAUR MARCH MADNESS 2k23!!!!!!!!!!!!

Starting NEXT WEEK, we begin the ultimate competition:

DMM: RISING STARS

These are ALL dinosaurs that have been discovered in the past five years!!! New friends from old times!!! Including such new fan favorites as Bajadasaurus, Jakapil, Meraxes, and Anachronornis - and that's only four of them!

From the weird to the wonderful, these dinosaurs are here to indicate that just because they were found recently, doesn't mean that they aren't destined to become icons like the names we already know and love. Get ready to learn about some new paleontological excitement - and debate angrily over which ones are better ;)

Round One will go from March 1st through the 7th

Round Two will extend from March 8th through the 14th

Round Three will then go from the 15th to the 21st

Round Four from the 22nd to the 28th

And the FINAL FOUR SHOWDOWN (Ornithischian Vs Sauropodomorph vs Nonavian theropod vs Bird) will occur from March 29th through April 4th!

Thanks to the new tumblr poll feature, reconstructions and mini factfiles for each dinosaur will be on the post with the poll itself! No need to leave tumblr, no personal research, no google quizzes - just rapid learning and immediate voting!

Get ready to vote! Get ready to debate! Get ready... for DINOSAUR MARCH MADNESS!

Round One Matchups under the readmore :)

Fossil Novembirb: Day 14 - Lost in the Woods

As the global climate was cooling during the Oligocene epoch, tropical rainforests started to shift towards their current distribution in the tropics, and open landscapes such as scrubland was spreading. But that doesn't mean forests were disappearing. In places like Central and Eastern Europe, forests shifted from tropical to temperate. And in these shifting landscapes, birds continued to adapt and diversify.

Turnipax: One of the earliest known members of a relatively obscure bird groups called buttonquails. Despite their quail-like appearance and lifestyle, buttonquails are shorebirds related to gulls and sandpipers.

Palaeotodus: This small insectivore is one of the first known members of the todies, a bird group nowadays restricted to the West Indies.

Primotrogon: An early member of the trogons which had a very different shape compared to its modern relatives, including long wings, a short tail, and relatively small eyes.

Eurotrochilus: The first known true hummingbird, a group now endemic to the Americas, but first appeared in Europe.

Aviraptor: A thrush-sized true hawk with long thin legs and sharp talons, this was a prime predator of small forest birds in the Oligocene.

Wieslochia: One of the earliest known passeriformes, a group that likely evolved in Australia,parts of it's skeleton resemble certain South American passeriforms, like cotingas.

Rupelramphastoides: As the earliest known ramphastid, it was closely related to the barbets as well as toucans, but it bore a closer resemblance to the former.

Oligocolius: A bizarre relative of modern mousebirds that had an appetite for seeds, as the holotype was preserved with seeds in its crop and gullet. It also had a slightly parrot-like beak.

Laurillardia: A distant relative of hoopoes and hornbills, this long winged and long tailed bird used its sharp beak to catch insects.

Rupelornis: A close relative of albatrosses, these seabirds had delicate beaks and long legs. They probably had a similar lifestyle to storm petrels, which carefully pick food from the surface of the water.

Factfiles:

Aviraptor longicrus

Artwork by @otussketching, written by @zygodactylus

Name Meaning: Long-legged Bird Thief

Time: 30 to 31 million years ago (Rupelian stage of the Oligocene epoch, Paleogene period)

Location: Jamna Dolna, Menilite Beds, Carpathian Flysch Zone, southeast Poland

Birds of prey are fascinating - there are many different kinds, doing many different things, and their radiation is poorly understood. Aviraptor helps put together some pieces of the puzzle by being the first raptor known adapted for eating birds as prey - essentially, capturing (larger) flying animals in the air, a not-easy feat. It was very similar to modern diurnal raptors, with a short beak, large laws, and long slender legs. That said, with those proportions it was very small - similar in size to living sparrowhawks and tiny hawks. It didn’t have a particularly hooked beak, but a straighter one similar to the harrier-hawks. It was similar, overall, to living birds that hunt early birds - and as such, it is the earliest known bird we know of to hunt other birds (oh bird on bird crime). Living alongside a variety of other birds, including passerines and hummingbirds, it probably fed on smaller avifauna in its area - and Aviraptor itself may have evolved in response to the radiation of many small birds in the early Oligocene. In addition to early modern-hummingbirds and crown passerines, Aviraptor lived alongside hoopoe-hornbill relatives, chickens, fish, and turtles.

Cryptogyps lacertosus

Name Meaning: Powerful Hidden Vulture

Time: 770,000 to 55,000 years ago (Chibanian to Tarantian stage of the Pleistocene epoch, Quaternary period)

Location: Throughout Australia, including Kalamurina, the Wellington Caves, and the Nullarbor Plain

Today, there are no vultures in Australia. In fact, until recently, it seemed fairly clear that no vultures had lived in Australia - but now, we know they did! Originally thought to be an eagle, Cryptogyps was on the small size for a vulture, only bigger than the living Hooded Vulture - though it was about the size of the wedge-tailed eagle. However, it was proportioned similarly to other vultures, and between that and its great range across the entirety of Australia, it is logical to conclude that it lived similarly to other vultures, feeding primarily on carrion and going great distances to find it. It did not have the right musculature to be an active hunter like eagles and hawks. As such, Cryptogyps was a vital part of its environment, reducing the spread of disease and recycling nutrients and energy back into the food web like vultures today. Cryptogyps lived alongside a wide variety of weird megafuana present in Australia during the last ice age, including marsupial lions, giant demon-ducks (mihirungs), giant hippo-sized wombats, sheep-sized and fossorial echidnas, short-faced kangaroos, giant koalas, thylacines, giant maleefowls, huge monitor lizards, large crocodilians, and giant pythons - as well as cassowaries, regular kangaroos, emus, and other large animals that remain today. It was a weird place of which Cryptogyps was a small and important part, and would have been a regular sight in the skies to the first Indigenous Australians to settle on the continent!

Aviraptor

Aviraptor — викопний рід хижих птахів родини яструбових (Accipitridae), що існував в Європі у пізньому олігоцені (31-30 млн років тому). Викопні рештки птаха знайдено в Польщі (село Ямна Долішня на південному сході країни). Рід містить один вид, Aviraptor longicrus. Його назвали в 2020 році Джеральд Майр (Gerald Mayr) і Йорн Хурум (Jørn Hurum) на основі…
