A new penis of the abelisauridae family of dinosaurs has been discovered . This grouping of dinos are expectant therapod carnivore characterize by their incredibly small-scale forearms – so lilliputian that they are often considered armless .
The novel specie , Guemesia ochoai , is the first discovered in Northwestern Argentina .
The researchers recovered a nearly complete braincase prove characteristics found in other abelisaurids , which have been break in South America , Africa , India , and Madagascar . The specimen date back to 70 million years ago , and back then , these regions were all fuse together in the southern continent of Gondwana .
The discovery is reported in theJournal of Vertebrate Palaeontology
The team also suggests some characteristics from the skull stay on that make it a discrete species . It is also 70 percent smaller than other abelisaurids , makingGuemesia ochoaithe small member of this family discovered .
“ This new dinosaur is quite unusual for its kind . It has several central characteristics that suggest that is a new metal money , provide important newfangled information about an area of the world which we do n’t know a pot about , ” Colorado - writer Professor Anjali Goswami , Research Leader at The Natural History Museum , enjoin in astatement .
“ It shows that the dinosaurs that dwell in this region were quite dissimilar from those in other part of Argentina , abide the idea of distinct provinces in the Cretaceous of South America . It also shows us that there is lot more to be find out in these field that get less attention than some of the more famous dodo sites . ”
The coinage live just before the end of the Cretaceous time period , when following an asteroid hitting our planet , 75 percentage of plants and animals went nonextant . That includes all the non - avian dinosaurs . So , studying this animal might give sixth sense into what the Earth was like back then .
In the region this unexampled specimen was fall upon , researchers have also recover fossilized specimens ofStupendemys geographicus , an ancient turtle and one of the largest ever nautical reptiles . investigator have also discovered Pisces the Fishes and mammal , and are currently working on describing them .
“ Understanding huge global events like a the great unwashed extinction requires world datasets , but there are lots of parts of the existence that have not been study in detail , and tonnes of fogy remaining to be discover , ” Anjali added .
“ We left some exciting fossil in the ground on our last head trip , not knowing that it would be years before we could get back to our field land site . Now we are hoping that it wo n’t be too much longer before we can land up digging them up and give away many more species from this alone fauna . ”
