Name: Panphagia protos 

Name Meaning: Eat all 

First Described: 2009

Described By: Martinez & Alcober

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha, Guaibasauridae 

Panphagia was a sauropodomoprh from the Ischigualasto Formation of Valle Pintado, Ischigualasto Provincial Park, San Juan Province, Argentina. It lived about 231.4 million years ago in the early Carnian age of the Late triassic. It is known from a partial skull and post cranial remains. It is known from a partially grown individual as well; the original skeleton was about 1.3 meters long, but fully grown adults would have been longer. It is one of the earliest known dinosaurs, and it may represent a transitional stage in the sauropodomorphs from a carnivorous diet to an herbivorous one. The teeth indicate that this animal may have been omnivorous, and had the beginnings of the leaf-shaped and serrated teeth used by sauropodmoprhs to procure plant matter.

“Short-necked Pan”
Late Jurassic, 150 million years ago (uncertain)

This unique sauropod measured only 30 feet in length. It set itself apart from its relatives with its unusually short neck – less than a quarter of its body length. While species like Diplodocus evolved longer and longer necks along the course of the evolutionary arms race, Brachytrachelopan practiced an adaptation strategy commonly known as “giving up.”

Chromogisaurus novasi

Source: askedmontonia

Name: Chromogisaurus novasi 

Name Meaning: Earth Color (Painted Valley) 

First Described; 2010

Describd By: Ezcurra 

Classification: Dinosaura, Saurischia, Eusaurischia, Sauropodomorpha, Guaibasauridae, Saturnaliinae 

Chromogisaurus was another sauropodmorph from the Ischigualasto Formation in Argentina. It lived in the Carnian age of the Late Triassic, about 230 million years ago. It is known from a partial skeleton which lacked a skull. It was an herbivore, about two meters long, and it could walk bipedally as well as quadrupedally. 

Also, sorry, I’m playing catch-up today for my absence - I had a busy couple of days! But that means we get three dinosaurs today! Woo!

“La Amarga lizard”
Early Cretacous, 129.4-122.46 million years ago

Amargasaurus was not large compared to its sauropod relatives; it grew to only about 33 feet in length. It stood out, however, because of its double row of long vertebral spines. Some experts have interpreted these spines as supporting sails, much like Spinosaurus, and others have suggested they were for thermoregulation. The current consensus is that Amargasaurus clattered the spines together as a sound display, making it the annoying toddler of the sauropod world.

“Giant giraffe”
Late Jurassic, 150-145 million years ago

Originally classified as a species of Brachiosaurus, this massive sauropod (of the titanosaur family) grew up to 74 feet long! For several decades it was the largest dinosaur known. Although it may have since been eclipsed in size, this majestic creature retains the dignity of dying before hearing itself called “Giraffatitan.”

Pantydraco caducus

Name: Pantydraco caducus

Name Meaning: Hollow of the Spring Dragon

First Described: 2007

Described By: Galton, Yates and Kermack

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha

Pantydraco was another sauropomodomorph dinosaur from the Late Triassic, specifically the Rhaetian age, and potentially into the early Jurassic, around 208 to 200 million years ago. It was originally described as a species of Thecodontosaurus and was only known from a skull and partial skeleton of a juvenile individual. However, understanding basal sauropodomorphs more lead to its reclassification and its own genus. It was probably an omnivore, and mostly bipedal. It was found in the Pantyffynnon quarry of Wales in the United Kingdom.

The Winton titan, Wintonotitan (2009)

Phylum : Chordata
Class : Reptilia
Order : Saurischia
Suborder : Sauropodomorpha
Infraorder : Sauropoda
Genus : Wintonotitan
Species : W. wattsi

  • Early Cretaceous (100 Ma)
  • 18 m long and 8 500 kg (size)
  • Australia, Winton formation (map)

For the last 75 years or so, Australia has been a relative wasteland when it comes to sauropod discoveries.

That all changed in 2009, with the announcement of not one, but two new sauropod genera: Diamantinasaurus and Wintonititan, comparably sized titanosaurs represented by sparse fossil remains. Like most titanosaurs, Wintonititan probably had a rudimentary layer of armored skin along its back, the better to deter the large, hungry theropods of its Australian ecosystem. (As to how titanosaurs wound up in Australia in the first place, tens of millions of years ago, this continent was part of the giant landmass Pangaea.)

“Chambered lizard”
Late Jurassic, 155-145 million years ago

Camarasaurus had a domed skull like Brachiosaurus, but the “chambers” referred to in its name are actually in its backbone – hollow vertebrae housed air sacs that reduced weight and helped such a large animal move. Its strong teeth would have been excellent for grinding tough vegetation, allowing it to occupy an ecological niche separate from its slender-toothed contemporary, Diplodocus. In fact, Camarasaurus was the most common sauropod of the Jurassic, and familiarity breeds contempt.

“Heavy lizard”
Late Jurassic, 152-150 million years ago

Although its neck was longer and its tail was shorter, Barosaurus was roughly the same size as its close relative Diplodocus. It was dubbed “Heavy lizard” because at 85 feet long and 20 tons, this powerful plant-eater still couldn’t escape reductive ideals of beauty.

…Apatosaurus was heavier.

“Broad lizard”
Triassic, 214-204 million years ago

Plateosaurus is considered a basal (basic/early) sauropodomorph (long-necked, quadrupedal herbivore like Diplodocus or Brachiosaurus). As such, many of its features make for an interesting crossroads in dinosaur evolution. One, it was still bipedal, probably only resting on its forelimbs while grazing. Two, it was almost certainly an herbivore (or omnivore), whereas its immediate ancestors were carnivorous. Three, it had bird-like air sacs in its bones, making it lighter and (at least partially) warm-blooded – traits otherwise recognized mostly in therapod dinosaurs. And four, it ranged in size widely – anywhere from 16 to 33 feet long for adults within the same species. While calling it a “missing link” between therapods and sauropods might be an exaggeration, it is safe to say that Plateosaurus couldn’t make up its damn mind.

Ruehleia bedheimensis

Name: Ruehleia bedheimensis

Name Meaning: Ruehle lizard

First Described: 2001

Described By: Galton

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha 

Ruehleia was a basal sauropodomorph from the Norian age of the Late Triassic, somewhere between 216 and 203 million years ago. It is known from scattered remains including the neck, back and tail, and partially complete hands. It was found in the Trossingen Formation in Germany. It would have been about 8 meters long and still would have walked around bipedally, though it may have gone on all fours for feeding and drinking. Its diet, like that of all early sauropodomorphs, is under some debate - while it could have been herbivorous like its descendants, some early members of the group may have been omnivorous while transitioning to a primarily herbivorous lifestyle.

Plateosauravus cullingworthi

Source: thewoodparable

Name: Plateosauravus cullingworthi

Name Meaning: Grandfather of Plateosaurus

First Described: 1932

Described By: von Huene

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha 

Plateosauravus was originally thought to be a species of Plateosaurus, however it was reassessed soon afterwards as a separate genus. As such, it was named in honor of the original genus; though it is unknown what its classification really is. It is known from more than a dozen partial skeletons, including juveniles. The exact age of the animal is unknown, however it did come from the Late Triassic. Furthermore, it was discovered in South Africa, including Kruger National Park.

Nambalia roychowdhurii

Source: My friend, thewoodparable, again! Seriously check him out! He has been instrumental in the 2015 Campaign for fluffy “prosauropods.” 

Name: Nambalia roychowdhurii 

Name Meaning: Named for the Indian village of Nambal 

First Described: 2011

Described By: Novas et al. 

Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha 

Nambalia was a sauropodomorph discovered in Andhra Pradesh in central India. It lived between the late Norian and earliest Rhaetian ages of the Late Triassic, around 208 million years ago. It is known from scattered skeletal remains and no heads, though there is material from multiple individuals. It was more primitive than Efraasia, Plateosauravus and Ruehleia, but more derived than Thecodontosaurus and Pantydraco. It was found with the plateosaurid Jaklapallisaurus, a guaibasaurid, and two dinosauriforms.
