The lower incisors are unicuspid, procumbent, sharp and delicate. "Fumana" shrubs can be procumbent or erect. "Arctostaphylos uva-ursi" is a small procumbent woody groundcover shrub high. The growth habit is prostrate / procumbent (trailing along the ground), but also climbing. The first pair of teeth is procumbent and larger than all others. The procumbent first dentary teeth fit between the first and second premaxillary teeth. The incisors, known only from "Ferugliotherium", are procumbent and long. The most distinctive characteristic of "Masiakasaurus" is the forward-projecting, or procumbent, front teeth. Stems are sometimes procumbent, often several per colony, forming colonies of several individuals. It is procumbent and compact and has smaller flowers but produces them in greater numbers. The stem keeps upright when short, yet becomes procumbent when tall. Unusually, the first several teeth in the dentary appear to be angled forwards, or procumbent. Some dinosaurs had procumbent teeth, which projected forward in the mouth. The unidentified lower front tooth is also enlarged and procumbent. The procumbent front teeth of the lower jaw project forward.
