It may sound like a joke, but it is pure science. In Montana, paleontologists analyzed a coprolite—petrified excrement—from 66 million years ago and found a microscopic treasure: the feather of a primitive bird. This marks the first time a dinosaur's 'menu' has been recorded with such biological precision.
In the wild landscapes of Argentine Patagonia, scientists have uncovered a prehistoric mystery. The discovery of 255 fossilized eggshell fragments from 68 million years ago reveals that the colossal Titanosaurs—some of the largest creatures to ever walk the Earth—employed a brilliant survival strategy to incubate their young without using their own massive weight.
A team of scientists has confirmed the first record of dinosaur footprints from the Coniacian period in Canada. The tracks, discovered in 1988 in a remote area of British Columbia, could only be studied in 2022. The finding fills a gap in dinosaur history and reveals a lost ecosystem.
A study published in Frontiers in Mammal Science reveals that Chiniquodon theotonicus, a mammal ancestor that lived in Argentina's La Rioja province 236 million years ago, might have given birth to live young. This discovery pushes back the appearance of viviparity in the mammalian lineage by 90 to 95 million years.
A study published in Frontiers in Mammal Science reveals that a cynodont found in La Rioja, Argentina, preserves a microscopic neonatal line in its bones. This suggests these mammalian ancestors gave birth to live young, pushing back the appearance of viviparity by 90 to 95 million years.
An exceptional fossil has revealed that Lystrosaurus, a dog-sized protomammal, survived the Permian-Triassic extinction over 251 million years ago thanks to its large, soft-shelled eggs. The discovery of an embryo inside the egg solves a long-standing paleontological puzzle and shows nature's incredible resilience.
