Research suggests more than 180 dinosaurs🦕🌿 preferred a plant-based diet, but it’s quite hard to put a precise number on it, says Paul Barrett, a paleontology researcher at the Natural History Museum in London.
in order to swallow high-energy foods whole. Bigger guts also tend to be a better fit for larger animals, which is one of the reasons why so many herbivorous dinosaurs were also the biggest in general.Clearly, not all dinosaurs were created equal. And not only are the different features of herbivorous dinosaurs distinct from what scholars see in carnivorous dinosaurs, says Button, but they also remind us of the breadth of diverse ways to exist as a plant-eating dinosaur.
“This unpicks the mechanisms that support diverse communities through evolutionary time,” says Button. “Also showing that some of the same ecological forces were patterning animal communities in the Mesozoic as today.”Regardless of whether we're talking about herbivores today or in the Age of Dinosaurs, most animals tend to eat plants. So if we don't understand what the plant-eaters are doing, says Barrett, we're missing a major part of that equation.
But, paradoxically, plant-eating is also the more-difficult path from an evolutionary standpoint. Although it's hard to catch animals to eat them, that's the hardest part about being a carnivore.

Shell agrees to pay $10 million for air pollution at massive new Pennsylvania petrochemical plantShell has agreed to pay $10 million to resolve allegations that it polluted the air around its massive new petrochemical refinery in western Pennsylvania. The administration of Gov. Josh Shapiro announced the penalty Wednesday. Shell acknowledged the plant violated air emissions limits. The multibillion-dollar refinery near Pittsburgh opened in November, only to be shut down months later after Shell said it identified a problem with a system that’s designed to burn off unwanted gases. Shell said it has fixed the problems, and plans to restart the facility. The plant makes polyethylene, a plastic used in everything from consumer and food packaging to tires.
