The Early Aptian (120 million years ago) was an age of intense volcanic activity on Earth, eruptions that emitted large amounts of CO2 into the atmosphere, thus causing a revolution in the carbon cycle. As a consequence, great changes happened in the whole of the terrestrial system. Researcher María Isabel Millán has studied how these changes happened in the marine environment of the Aralar mountain range (at that time it was under the sea) in the Basque Country, and...

Sauroposeidon, meaning “earthquake god lizard,” is a genus of sauropods dinosaur from the Aptian and Albian ages of the Early Cretaceous Period (110 million years ago). It was discovered in the southeast region of Atoka County, Oklahoma, not far from the border of Texas, in a claystone outcrop. The fossils were initially misidentified as pieces of petrified wood when they were found in 1994. A more detailed analysis in 1999 revealed they were truly dinosaurian bones. They were formally...

The type species, X. baimoensis, was described in 2009 by a group of researchers from China and the USA. The species name, baimoensis, means "white ghost", after "white ghost castle", a rock formation near where the fossil was found. Xiongguanlong was a medium-sized tyrannosauroid. It...

Paul stated that it was more closely related to Ouranosaurus than Iguanodon. It is known from many partial and nearly complete skeletons. The genus name honors Gideon Mantell, the discoverer of the Iguanodon. Mantellisaurus was smaller...
