Chilesaurus, a plant-eating theropod from the Jurassic

Seems rather similar to Limusaurus and maybe Elaphrosaurus?

I've read somewhere that there was once a strange quadrupedal theropod, in form resembling a sauropod more than anything else...This theropod, like Chilesaurus, was also a herbivore. Can't remember for the life of me what this dino was called, but I'll try to retrieve the info about him...Until then, can anyone find something about this dinosaur?

You might be thinking of Segnosaurus, which was a real puzzle for a while, and was often depicted as being quadrupedal:



Other similar theropods like Erlikosaurus known from very fragmentary remains were also depicted as quadrupedal and prosauropod-like:



Today we know they both belonged to family Therizinosauridae and were most likely fully bipedal.
