#Archovember Day 25 - Massospondylus carinatus

Massospondylus was an early sauropodomorph, and one of the first dinosaurs to be named, in 1854!

Early sauropodomorphs were bipedal, and some may have even been omnivorous. Not quite as tall as it’s sauropod descendants, Massospondylus was still pretty big, at about 13 to 20 feet long it would have been able to stretch its long neck into the trees of the Southern African desert. It had a long, sharp thumb claw on each arm that could have been used for combat, to strip bark from trees, or even to dig.

Since 1976, at least 10 Massospondylus egg clutches have been found, with up to 34 eggs per clutch. Some fossilized embryos of these little sauropods were able to be extracted and examined, and had short, stubby proportions, big heads, and large eyes. Based on hatchling footprints near a nest site and the forelimb anatomy of the embryos, it was determined that hatchlings would have walked on all fours until they could support themselves on their hind legs. These remain the oldest dinosaur embryos ever found.

We present you our own #Dinovember 2020 prompt! 🎨

Every day of November you can draw one of the suggested creatures or something from the same family. Example: Day 5 I could either draw the suggested Alioramus or another tyrannosaur like Daspletosaurus.

We decided to use not-so-well-known families and species of dinosaurs to help them being more represented in the collective imaginary.

We hope you like it and feel free to tag us so we can see your work! Good luck!

It's #Dinovember so here's a feathered raptor Diego Brando! Or should we say, a Dio-saur? A Dio-nychus?

DINOVEMBER HAS COME

1 - Tototlmimus packardensis (From Nahuatl "tototl" - bird - and Latin "mimus" - mimic) - Late Cretaceous (72 Ma BCE) - Packard Formation, Sonora, Mexico

Formally described in 2016, Tototlmimus is one of the most recent genera of ornithomimosaurs native to North America, described from a partial skeleton without skull, placing it closer to the genus Ornithomimus, from the end of the Cretaceous, being approximately the size of an rhea. The Packard Formation, where it was found, was probably a large coastal plain, crossed by river deltas where this animal probably fed, using its long neck and toothless beak to catch aquatic vegetation and animals like lizards and amphibians that lived there, like a great heron or stork. Ornithomimosaurs are theropods specialized in running, having long rear legs with three fingers, suppressing the first finger - hallux - as a way to free its legs from the extra weight, allowing them to reach speeds in 30 and 70 km/h, being among the faster non-avian dinosaurs. Despite being theropods, related to large carnivores, these dinosaurs were probably omnivorous or entirely herbivorous, losing teeth throughout their evolution, using their longs necks and arms to reach their food in trees or bodies of water. The presence of feathers in these animals, similar to ostrich feathers, is practically confirmed by impressions on some fossils in addition to the evolutionary heritage, being members of Coelurosauria, the dinosaurus closest to birds. Underneath these feathers, there would be the presence of a bare skin without scales, similar, again, to an ostrich.

#Archovember Day 7 - Vegavis iaai

Listen. I know what you’re thinking. “But... Sarita, this is just a goose.”

Here is what’s special about this goose. First of all it’s not a goose, but a close relative. We don’t have a skull, but we do have a syrinx that shows it was capable of honking. But here’s the most special part: it lived in Antarctica... during the late Cretaceous.

This means it lived at the same time as ankylosaurs, hadrosaurs, ceratopsians, dromaeosaurs, and tyrannosaurs: some of the most famous dinosaurs!

Among many other bird species from this era, Vegavis shows us that at this point birds were already in the diverse groups they are today. T. rex could have hunted waterfowl, small birds could have pecked at Spinosaurus’ teeth to clean them, the giant Quetzalcoatlus would have shared the skies with these small, agile dinosaurs.

Vegavis serves to remind us that we are very lucky to have this huge diverse group of dinosaurs still sharing this planet with us today.

So next time you get chased by an angry goose, remember that that angry goose’s ancestors probably had to chase raptors away from their nests... and those angry geese probably won. And just look at which lineage survived extinction...

#Archovember Day 8 - Geosternbergia sternbergi

Since I did Pterodactylus, I wanted to also include a Pteranodon, as those two pterosaurs seem to be the only ones the average layperson knows about. However, Geosternbergia has a cooler crest, in my opinion, and it’s close enough (it could be considered to either be a species of Pteranodon, or its direct ancestor.)

Geosternbergia was one of the largest pterosaurs. On all fours, an adult male could have stood as tall as a human, and in flight could have had a wingspan of up to 19.7 ft! They were extremely sexually dimorphic, with the males being twice as large as the females, and with bigger crests.
