Lakeshore sites such as Cerro de la Garita (Miocene of Teruel, Spain) and Sen猫ze (Pliocene of Haute-Loire, France) yielded fossils with distinct puncture marks. These marks were described as 鈥減unctures surrounded by plastically deformed bone鈥? and were proposed to have been caused by compression or trampling on bones against coarse sediment grain when deposited in damp environments. A series of experiments was performed to test this hypothesis. Cow, red deer and fallow deer metapodials were compressed by applying a mechanical load on them against a gravel substrate under dry/damp environments. Results confirm that these characteristic puncture marks are associated with compression efforts on bones in wet environments.
