If you thought climate change is a recent problem, then you might have to rethink your belief because an interesting study has recently revealed that climate change may have been the reason behind late emergence of plant-eating dinosaurs.

It is being believed that plant-eating dinosaurs probably arrived in the northern hemisphere millions of years after the meat-eating species.

This delay of millions of years in the emergence and the migration of dinosaurs was probably caused due to climate change, scientists believe.

A new way of calculating the dates of dinosaur fossils revealed that plant-eating dinosaurs, sauropodomorphs, were actually 215m years old and not 228m years old, as it was previously believed.

This has changed the previous belief and has revealed that there might not be any plant-eating dinosaur family in the northern hemisphere which was more than 215m years old.

On the other hand, examples of meat-eating dinosaurs have been found dating back to at least 220m years ago.

The study lead author Dennis Kent of Columbia University believes the plant-eating dinosaurs were latecomers in the northern hemisphere.

As per his team's research, during the Triassic era — which was nearly 230m years ago, carbon dioxide levels were 10 times higher than the present day. the atmosphere was hotter with no ice sheets at the poles and two bands of extreme deserts on both sides of the equator — north and south.

This dryness might have led to fewer plants for the sauropodomorphs, making it difficult for them to survive the journey. The meat-eaters, on the other hand, had enough insects to survive.

Later, when carbon dioxide levels dropped to half nearly 215m years ago, plants started growing in the deserts, which led to the emergence of sauropodomorphs in the area.

Migration of meat-eating dinosaurs was delayed by million years. Why?

Researchers announced on Wednesday they have discovered a ferocious meat-eating dinosaur in Argentina, notable for having short arms like the T-rex but hailing from a different branch of the family tree. 
 
The Gualicho shinyae -- nicknamed Gualicho -- is a theropod, a two-legged, bird-like dinosaur. It stretched an imposing six metres (nearly 20 feet) from head to toe&nbsp;and weighed an estimated 450 kilograms (1,000 pounds). 
 
It roughly resembles the Tyrannosaurus rex but Gualicho, found in the north of Argentina&#39;s Patagonia region, was not a close relative of the king of dinosaurs. 
 
Its stubby limbs evolved independently and not from a shared, short-armed ancestor -- a clue that may help researchers better understand how the extinct animals evolved. 
 
&quot;This is a completely different lineage. We just froze up when we realised it,&quot; Sebastian Apesteguia, a researcher at Argentina&#39;s National Scientific and Technical Research Council told a briefing in Buenos Aires. 
 
It&#39;s only known ancestor is the Deltadromeus, a leggy, carnivorous dinosaur with slender arms found in Niger. 
 
The research on Gualicho in the scientific journal Plos One was led by Apesteguia and Ruben Juarez Valieri, a specialist in carnivorous dinosaurs in Argentina&#39;s Rio Negro province. 
 
The new dinosaur&#39;s name Gualicho is in honour of a local indigenous deity with power over animals and the wind. And Shinyae is in honour of Akiko Shinya, chief fossil preparator at Chicago&#39;s Field Museum, who found the incomplete skeleton while working on the dig. 
 
&quot;We found Gualicho at the very end of the expedition. Pete joked, &#39;It&#39;s the last day, you&#39;d better find something good!&#39; And then I almost immediately was like, &#39;Pete, I found something.&#39; I could tell right away that it was good.&quot; 
 
She was referring to Peter Makovicky, The Field Museum&#39;s curator of dinosaurs. 
 
&quot;Gualicho is kind of a mosaic dinosaur, it has features that you normally see in different kinds of theropods,&quot; Makovicky said in a statement. 
 
&quot;It&#39;s really unusual -- it&#39;s different from the other carnivorous dinosaurs found in the same rock formation, and it doesn&#39;t fit neatly into any category.&quot; 
 
&quot;By learning more about how reduced forelimbs evolved, we may be able to figure out why they evolved,&quot; Makovicky added. 
 
Most of the recovered fossils are in the Patagonia National Sciences Museum and a provincial museum in the Argentine city of Cipolletti.
