Dinosaurs, pterosaurs & marine reptiles of Isla Sorna

Just a friendly reminder about this week's quiz question. You've been asked: What was the name of the superocean that once encompassed the Earth and surrounded the supercontinent Pangaea? Tethys, Mirovia, Panthalassa, Khanty, Iapetus or Ural?


Today's dino:


Name: Chondrosteosaurus
Pronunciation: Kon-dro-ste-oh-sore-us
Meaning of name: "Cartilage and bone lizard", as it was once thought that the internal passages in the vertebrae were filled with cartilage.
Species: C. gigas
Size: Uncertain due to a lack of fossils.
Family: Uncertain
Diet: Herbivore
First fossils found: Known only from neck vertebrae discovered in the Wessex Formation of the Isle of Wight, England. Named by English palaeontologist, Sir Richard Owen, in 1876.
Lived: 125 million years ago during the Barremian stage of the Early Cretaceous in what is now the Isle of Wight, England.

Finally getting the chance to see a real T-Rex fossil.

A little similar to modern birds.

A final reminder about this week's quiz question before the answer is revealed tomorrow. You've been asked: What was the name of the superocean that once encompassed the Earth and surrounded the supercontinent Pangaea? Tethys, Mirovia, Panthalassa, Khanty, Iapetus or Ural?


Today's dino:


Name: Antarctosaurus

Meaning of name: "Southern lizard"
Species: A. wichmannianus
Size: Estimated to have measured around 33 metres long and weighing 67 metric tonnes.
Family: Antarctosauridae
Diet: Herbivore
First fossils found: Known from numerous fossils discovered in Argentina, Brazil and Uruguay. Named by German palaeontologist, Friedrich von Huene, in 1929.

Tix Mascot , LadyPorthos , Joey , well done for correctly guessing the answer to this week's quiz question. You were asked: What was the name of the superocean that once encompassed the Earth and surrounded the supercontinent Pangaea? Tethys, Mirovia, Panthalassa, Khanty, Iapetus or Ural?


Answer: Panthalassa. Meaning "All sea", Panthalassa covered nearly 70% of the Earth's surface (360 square kilometres), with the supercontinent Pangaea taking up less than half.


Today's dino:


Name: Anoplosaurus
Pronunciation: Ah-no-plo-sore-us
Meaning of name: "Unarmoured lizard" or "Unarmed lizard", as it was once thought to have not had any armour.
Species: A. curtonotus
Size: Estimated to have measured around 5 metres long.
Family: Nodosauridae
Diet: Herbivore
First fossils found: Known mostly from vertebrae discovered in the Cambridge Greensand Formation of eastern England. Was thought to be a relative of Iguanodon, as its fossils, when first discovered, were mixed with those of a Camptosaurid. Named by British palaeontologist, Harry Govier Seeley, in 1879. Originally thought to be a species of Acanthopholis.
Lived: 100 million years ago during the Cenomanian stage of the Late Cretaceous in what is now eastern England.

This one is too much to handle. I prefer Sindbad the cat.

Name: Barrosasaurus
Pronunciation: Bah-ross-ah-sore-us
Meaning of name: "Sierra Barossa lizard", after the place in Argentina where its fossils were discovered.
Species: B. casamiquelai
Size: Uncertain due to a lack of fossils, but is estimated to have measured around 18 metres long and weighing 13.5 metric tonnes.
Family: Uncertain. Likely Titanosaurid.
Diet: Herbivore
First fossils found: Known only from three partial back vertebrae discovered at "Sierra Barossa" in the Anacleto Formation of Neuquén Province, western Argentina. Named by Argentine palaeontologists, Leonardo Salgado and Rodolfo Aníbal Coria, in 2009.
Lived: 83.6 to 72.1 million years ago during the Campanian stage of the Late Cretaceous in what is now western Argentina.








New quiz question: In which African country have fossils of Heterodontosaurus been discovered? Cameroon, Angola, Somalia, Namibia, South Africa, Togo, Sierra Leone or Seychelles?
