Are either of these possibly human molars? If so, would they be recent, Native American, or perhaps older? If not, what do you think they are? They were found on the Potomac river, in Purse State Park, in southern MD on separate trips about a year apart.
Good as I can not buy my dinosaur egg what do you think of this molar mammoth? Excellent Miocene Mammoth molars, an extinct elephant ancestor with long, curved tusks that evolved in the Pliocene of North America. These large mammoth molars were found in Florida. Authenticity guaranteed. A GEM Pleistocene Mammoth molar. The Mammoth, an extinct elephant ancestor with long, curved tusks that evolved in the Pliocene of North America. This large molar with an incredibly articulated chewing surface. Complete root. An exceptionally well perserved specimen. Well fossilized. Weighs 7 lbs. No damage. No repair.
Hello! I am a newbie to the fossil hunting world transferring over from rock hunting. I found a few fossils on the Sulfur River yesterday and am hoping to get help in identifying them as close as possible to the original species.
Horse Teeth 'Modern' horse teeth are very hypsodont (high-crowned) to deal with wear caused by eating gritty and/or fibrous foods like grasses. A mature horse may have as many as 44 teeth, which include: 12 incisors (6 upper and 6 lower) Canine teeth are usually absent in female horses but may be present in males. Cheek teeth (4 premolars and 3 molars per side) have very complex enamel patterns. The first premolars (upper and lower) in horses (sometimes called the 'wolf teeth') are vestigial and often absent. Upper cheek teeth (premolars and molars) can be recognized by the relatively square shape (except for the second premolar and third molar) when viewing the occlusal (chewing) surface. Lower cheek teeth (premolars and molars) can be recognized by the relatively rectangular shape when viewing the occlusal (chewing) surface (except for the second premolar and third molar). Horse 'foot' bones 'Modern' horses are monodactyl (one-toed). The metapodials (hand and foot bones) are reduced to a single unit on each leg. There are three 'toe bones' - phalanges (singular is phalanx) on each foot...phalanx I, phalanx II and phalanx III. The third phalanx is the 'hoof core' Unfortunately, I have never collected an intact phalanx III so I have not pictured one here. The astragalus (ankle bone) is only present on the hind legs.
Two Bison sp. third lower molars of different age. This is the last tooth to emerge at maturity. The younger individual had not worn its teeth much . . . tooth wear has not reached the diagnostic isolated stylid. The older individual has worn its teeth enough to engage the isolated stylid. Note that the tooth of the older individual retains some cementum. In life, all the bison cheek teeth were wrapped in cementum. Being the softest of the three types of tooth components (enamel, dentin, and cementum), this exterior 'wrapper' is often lost on a fossil.
