Over the last quarter century , a squad of paleontologists has compile and studied coprolite — fossilize poop — and dinosaur vomit , millions of year older , from what is now Poland . The squad has now published its findings , break hitherto unknown details of the relationships between the giant reptilian and their home ground .
As the dinosaur live , they pooped and occasionally upchucked . In these bodily fluids ( and solids ) the out reptile entrust evidence of their dieting , and by proxy , their surround . The team studied the dinosaur ’ deposits using synchrotron imaging , which reveal the concealed interiors of the fossilized feces . The squad discovered what the fauna ate , but also painted a picture of a belt of Pangea between 230 million years ago and 200 million years ago , as the Triassic Period was collapse mode to the Jurassic . The team ’s findings werepublishedtoday inNature .
“ Our findings discover that other dinosaur dominance was not a straightforward operation but rather a complex transition shape by factor such as bionomic opportunism and competition with other animals , ” said Martin Qvarnström , a researcher at Uppsala University and atomic number 27 - generator of the discipline , in an electronic mail to Gizmodo . “ This reshapes our understanding of how dinosaurs adapt and rose to prominence in a dynamic and competitive Triassic world . ”

About 230 million years ago , Poland was part of the supercontinent Pangaea . Dinosaurs , plants , fish , insects , and other living things eked out existence on its shore . There , those organism left ghost of their existence — in footprints and bite marks but also in masticate - up organic topic and demolish bones which ended up excrete or expectorated by the dinosaur .
“ 25 year ago I would not have stargaze that I would travel with kilograms of fossilized dinosaur feces to the synchrotron in Grenoble , and utilise this advanced instrument to study the Triassic and Jurassic dinosaurs of Poland , ” enunciate Grzegorz Niedźwiedzki , a researcher at Uppsala University and go author of the study , in an email to Gizmodo . “ We were as happy as children spread Christmas presents at every find of a coprolite . ”
The team charter hundreds of coprolite sample to a synchrotron to visualise their internal bits — specifically seeking undigested intellectual nourishment . The coprolite of heavy herbivores — sauropods , to be precise — storm the team . The coprolite contained ferns and other plant , but also charcoal . The team posited that the animals may have consumed wood coal to protect themselves from toxins that may have been present in the ferns .

“ Firstly , we could see for the first time what these early dinosaur ate , secondly , what they ate from the plants that grew in the Triassic and Jurassic ecosystem , and thirdly , what is even more interesting , among these plant remains find oneself in the coprolite quite a little were many whose fogy do not go on in the sites where we found the coprolites , ” Niedźwiedzki added . “ The dinosaurs in all likelihood fed in a different place than the one where we discovered their fossilized feces . ”
The squad believe that more info may still be hidden in the coprolites ; thankfully , synchrotron imagination is non - invasive , so the investigator can go back for seconds . Besides revisit the coprolite , there is a site from the early Jurassic that Niedźwiedzki said was “ a real treasure trove . ”
“ To this twenty-four hour period we have dig up several thousand dinosaur tracks there , ” he said . “ We have something to do for the next 25 years . ”
The dinosaur were wipe from the face of the Earth 66 million years ago , when an asteroid — and perhaps two — smash into the planet ’s surface , kick upa mega tsunamiand dust , soot , and atomic number 16 thatblotted out the Sun . But the dinosaurs ’ dying chance about 150 million age after the moments in deep fourth dimension captured in the recently interrogated coprolites .
In other words , there are still 1000000 of years of history that may be interlock away in yet - to - be - excavated dinosaur poop and hurl . It ’ll take longanimity , luck , and a bit of time with the synchrotron , but we may yet acquire more about the Clarence Shepard Day Jr. of the dinosaurs through their rejectamenta .
