Oh! Rice, I was walking across street, from Museum, & could hear this strange, roaring noise!
It was the head mov't which attracted me!
It was the 'Muttaburrasaurus', out for a 'stroll' in the Courtyard! It mesmerised me, & I spent several minutes' watching, & listening to him!
It was a marvellous experience! Cheers!
I suppose it would depend upon what it would have looked like, where it lived, what it ate, whether it was land based. These are the usual criteria for scientific names. For any other name, I have no idea.
