One of the big plant-eating dinosaurs similar to Camarasaurus, Euhelopus, or "good marsh foot," had a longer neck and nose. Like Camarasaurus, it had strong teeth that grew around its jaws. Other dinosaurs of this type had teeth growing only in front. Euhelopus had large nostrils on top of its head. Because of this, some scientists think it had a long trunk. That would have made it look very strange. Both Camarasaurus and Euhelopus were camarasaurid (chambered lizard) dinosaurs, with hollow chambers in the backbone.

Euhelopus was a little slimmer than Camarasaurus, but large members of the family may have weighed as much as 24 tons. The biggest could have been up to 50 feet in length - without trunk. From fossil remains, scientists believed they were at home in marshy land at the bank of muddy rivers or in swamps. They would have been safer there than on dry or wooded land where big flesh eater roamed.
