The extraction of this slab from rocks in Texas represented the first major fossil footprint excavation in the history of paleontology. The 20th century in ichnology refers to advances made between the years 1900 and 1999 in the scientific study of trace fossils , the preserved record of the behavior and physiological processes of ancient life ...
Adding to this conundrum are fossilized footprints of bird-like tracks that are 210 million years old—a good 60 million years before the arrival of the genus Archaeopteryx, one of the oldest ...
The fossils were discovered in the mountains of northern Italy's Lombardy region after the snow and ice that once covered them melted away, scientists say, as a result of the ongoing climate crisis.
The Connecticut River Valley trackways are the fossilised footprints of a number of Early Jurassic dinosaurs or other archosauromorphs from the sandstone beds of Massachusetts and Connecticut. The finding has the distinction of being among the first known discoveries of dinosaur remains in North America.
