Bear claw marks, TWH19 . Determining the age of these #claw marks would be challenging. First one would want to take into account the situation of their occurrence. These were found in a #cave, not far from the surface, in a stream passage. Slots like closets flank the sinews of the passage, each filled with mud and silt up to the ceiling. Beginning at about five feet from the floor marks a line below which no claw marks are present. Above the line the claw marks are common. . Why the line? Bears haven't occupied the cave for sometime, perhaps the cave was abandoned during the historic era as bears were hunted. Perhaps the entrance bears entered through hasn't been open in thousands of years. The line represents the largest floods that have happened since bears stopped coming to the cave. The floods would have removed the evidence of their claw marks which were certainly as common below the line as above. . What species of bear? I do not know. It may be a modern species, it may be a species from the pleistocene. I'm leaning towards a modern species. . #bear #wildlife #tracefossil #cavve #caving #nsscaves #conservation #science #paleontology #biology #zoology #investigation #discovery #geology #karst . @natgeo @nsscaves https://www.instagram.com/p/B7TRNljBIz7/?igshid=z2ggjwz3z2dx
