A super-constipated Florida reptile has broken the record for the largest mass of feces ever discovered in a living animal — relative to its size, that is.

The chunky curly-tailed lizard had been feasting on a steady diet of pizza grease, sand and insects, clogging her innards with a T-Rex-sized turd, according to a report published in the Herpetological Review journal.

When scientists at the University of Florida first discovered the rotund reptile near a Cocoa Beach pizza joint, they assumed she was pregnant and about to give birth.

But when they went to check for eggs, “it just felt like it was full of Silly Putty,” said researcher Natalie Claunch in a statement.

A CT scan revealed the lady lizard was bursting with 22 grams of poop — accounting for 80 percent of its total weight.

It was the largest known feces-to-body-mass ratio recorded in a living animal, the scientists said.

“I was blown away by how little room there was left for all the other organs,” Florida Museum researcher Edward Stanely says in the statement.

“It has only a tiny space left over in its rib cage for the heart, lungs and liver.”

The pear-shaped dino descendant must have been very ‘saur — as she was left unable to digest the nutrient-depleted blob, and appeared to be starving.

To better understand her condition, the researchers had to humanely euthanize her.

But she’ll live on in history books.

“We are unaware of any records from wild or captive animals that approach our finding,” Claunch told Inverse.

“We hope for the sake of the individual animals that there are not any out there!”
