analyzed data on injury-related incidents submitted voluntarily by 347 (87%) of 398 member drilling companies to the International Association of Drilling Contractors (lADC), an international trade association that represents the oil and gas drilling industry.
The molars are very narrow in proportion to their length, and retain little occlusal detail even in young animals, the cusps and lophs
wearing rapidly away to dentine.
In the American mastodon [Dp.sup.4.sub.4], M 1/1 ,and [M.sup.2.sub.2] each consist of three transverse ridge crests, or lophs
, which are formed by two cusps.
The teeth are triangular in cross section with the mesial and distal lophs
of the occlusal surface converging towards the apex of the triangle, a feature characteristic of megalonychid sloth teeth.
The paraloph and metaloph are weaker and shorter than in Nyctinomops, in which the two prominent lophs
converge and nearly reach the protocone.
For age determination we followed Libardi (2013) and Voss (1991), and recognized 5 classes defined by tooth eruption and wear of major cusps, lophs
D4: Tooth with five lophs
. The anteroloph low connected to the protoloph at the labial border.
