A Dinosaur A Day

A Field Guide To Dinosaurs

dinostuck:

Hey Guys,

I’ve had some really bad internet connectivity problems which has made it impossible for me to do things like update a dinosaur a day

That, in tandem with me applying to graduate school, has made me SO busy I can barely think

I’ll try to come back online some time this week. We’ll see how it works out

Love,

Meg

Chilantaisaurus tashuikouensis

NameChilantaisaurus tashuikouensis

Name Meaning: Chilantai lizard

First Described: 1964

Described By: Hu

ClassificationDinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Carnosauria, Allosauroidea, Allosauria, Carcharodontosauria, Neovenatoridae

Chilantaisaurus was a neovenator theropod from the Turonian age of the Late Cretaceous period, about 92 million years ago. It was found in the Ulanshuhai Formation of China, and it was a large theropod, weighing between 2.5 metric tons and 4 metric tons. It actually has a really complicated taxomic history, as many of the bones attributed to its initial remains were actually from other species. Also, the type species has been interpreted as being from many different groups, such as spinosaurids and coelurosaurians. It is not, however, the same animal as the carnosaur Shaochilong, as the two have majorly different sizes and different features.

PALEON dino card game on kickstarter

Hey, I just backed a cool dino game and thought I’d let others know about it. It’s a strategy game, but each card has a description of the dinosaur/prehistoric animals and all the illustrations are 3D CG! (Of course, they’re paper, so they’re not actually 3D. Haha.) I think that’s pretty cool for 16 bucks though.

Massospondylus carinatus, M. kaalae

NameMassospondylus carinatus, M. kaalae 

Name Meaning: Longer vertebra

First Described: 1854

Described By: Owen

ClassificationDinosauria, Saurischia, Eusaurischia, Sauropodomorpha, Plateosauria, Massopoda, Massospondylidae 

Requested by Jamesz3! 

Massospondylus was a prosauropod dinosaur from the Hettangian to Pliensbachian ages of the Early Jurassic, from about 200 to 183 million years ago. It is known from a plethora of finds, ranging from the Upper Elliot Formation in Lesotho, the Clarens Formation in South Africa, and the Forest Sandstone Formation, Mpandi Formation, and Upper Karroo Sandstone Formation in Zimbabwe. It was found very early in the history of dinosaur discoveries, and used to be a wastebasket taxon as a result. It was between 4 and 6 meters long and could range from about 1 meter high to 2 meters high when walking bipedally. Recently, it was found to be primarily bipedal, though previously it was depicted as quadrupedal. This is due to the limited range of motion produced when it was in a quadrupedal stance, and the inability for the forelimbs to swing in a similar way to the hindlimbs. In short, Massospondylus could not pronate its hands, a necessary requirement for walking quadrupedally.

Massospondylus was initially considered to be herbivorous, but it also was possibly omnivorous. It probably was not carnivorous, and its teeth were more similar to those of herbivores than carnivores. It has been found with gastroliths, however, its not likely that they were used as gizzard stones given their abundant and polished nature. Massopsondylus eggs have been found in a clutch of seven and they are the oldest dinosaur embryos ever fine. Other sites have also been found with up to 34 eggs per clutch. Nesting sites were probably used repeatedly by groups of animals, and this is the oldest evidence of that pattern of behavior. The eggshells were very thin and were partly buried in substrate. The eggs were arranged in specific patterns but not in nests. Hatchlings had very large heads with short snout and large eyes, and forelimbs of equal length to the hindlimbs, allowing for quadrupedal motion. It has even been suggested that quadrupedal sauropods evolved due to a retention of juvenile quadrupedal character in prosauropods. Footprints of the young have been found, confirming this phenomenon. They had no teeth, and thus could not care for themselves; it was necessary for the parents to feed and protect them until they doubled in size.

Massospondylus, unlike its close cousin Plateosaurus, exhibited a specific growth trajectory, with little variation in rate or ultimate size of the individual. It grew until it was 15 years old. It probably used its short forelimbs as defense against predators, and they probably also assisted in feeding. Massospondylus probably fed on many conifers, and lived in a universally hot climate. It lived alongside rauisuchians, crocodylomorphs, tritylodontids and trithelodontids, morganucodontid mammals, and other dinosaurs such as MegapnosaurusLesothosaurus, and Abrictosaurus, Heterodontosaurus, Lycorhinus, and pegomastax. It also lived alongside the prosauropods Ignavusaurus and Arcusaurus. It probably was preyed on by Dracovenator, since Megapnosaurus was much smaller than it; unless Megapnosaurus hunted in packs.

Coming soon: SciNote.org, launched by entrop-e, shychemist, and geogallery, is Tumblr’s project for promoting science education around the world.

At SciNote, we believe that science shouldn’t just be reading about the ideas of people with PhDs and Nobel Prizes. We believe that science is an active process of asking questions and finding answers.

That’s why we, at SciNote, want to hear from you. We want to ponder the interesting questions you pose and get excited with you over the cool science you see in your world.

SciNote will feature the best of the Tumblr science community, and we will compile and publish the top posts from every year in the form of a magazine available both digitally and in print. Think of SciNote magazine as the Tumblr science magazine.

We hope to celebrate our launch by featuring some of the coolest science from around Tumblr. So before we launch SciNote, we would like to collect 25 science posts and/or questions from you, including:

  • the most interesting science news you have come across
  • questions you’ve always wanted to ask
  • fascinating facts that you’ve learned
  • pictures of nature and/or science that you’ve taken
  • cool research that you’ve participated in
  • any other science-related thing you’d like to tell us!

So please:

  1. Submit posts or ask questions to be featured on our blog and for an opportunity to be published in SciNote magazine.
  2. Follow our blog at SciNote.org.
  3. Read more about our project here.
  4. If you’re interested, apply to join our staff here.
  5. Reblog this post so that we can collect 25 posts and launch our project as soon as possible!

Pisanosaurus mertii

NamePisanosaurus mertii 

Name Meaning: Merti & Mr. Pisano’s lizard

First Described: 1967

Described By: Casamiquela

ClassificationDinosauria, Ornithischia, Pisanosauridae 

My Twelfth Favorite Dinosaur! 

Oh look another basal dinosaur what a surprise. Pisanosaurus is considered to be the basalmost ornithischian, or at least the basalmost one known to date. It lived between 228 and 216.5 million years ago in the Norian age of the Late Triassic period. It was found in the Ischigualasto Formation in Argentina and it was a small, lightweight, bipedal herbivore about 1 meter long. Its classification has been under a lot of debate but the current consensus is that it is the oldest known ornithischian. It is only known from a single skeleton that is known from a partial skull and some teeth, some vertebrae, and other bones including part of the pubis, allowing for its classification. Given the synapomorphic character of protofeather/feather like integuments it probably was covered with them in at least some parts of its body. It lived in a volcanically active floodplain that was covered with forests and was warm and humid, but subject to seasonal rainfalls. It probably ate the vegetation of the area which consisted of ferns, horsetails, and conifers. Its major predator was probably Herrerasaurus, which was the most common predator in the area. Pisanosaurus lived right alongside therapsids, rhynchosaurus, dicynodonts, traversodontids, rauisuchians, archosaurus, Saurosuchus, and Eoraptor as well as Herrerasaurus. Herbivorous dinosaurs such as Pisanosaurus were definitely in the minority.

My tenth favorite dinosaur is Allosaurus 

which I have already done 

And my eleventh favorite dinosaur is Megapnosaurus

I’ve been sitting here at my desk debating and mulling and wondering what to do

What I will do 

Is my 12th favorite dinosaur
