Dog, Coarse sand, Tenerife

Dog track made on the beach. Notes: The sediment collapse between the digits is interesting, especially if you consider how this might be interpreted from the fossil track record without knowing the track maker.沙滩上留存的犬类足迹。备注：趾间沉积物的塌陷现象颇具研究价值，尤其是在未知造迹生物的前提下，若通过化石足迹记录对该足迹进行成因解读时，这一特征的研究意义便尤为突出。
