The main legs fold inwards; when deployed, they splay out strongly. Splitting the toebox helps allow toe splay and gripping. The siltstones and mudstones represent crevasse splay, overbank and shallow pond environments. Crevasse splay deposits can range in size. Thus, loss of posterior teeth will cause the anterior teeth to splay. The walls have a brick plinth with red splay bricks. Two capitals have trapezoidal-plant abacus and perhaps adorned a window splay. Some moccasins have wide, unstructured toeboxes, somewhat loose on the foot, which allow toe splay. Its arms and legs splay out in the standard anuran body form. This event generated a liquefacted crevasse splay deposit which entombed the two dinosaurs. The heels of the spars are secured by splay and heel tackles. RNAV T-route airspace and protection areas do not splay with distance from the waypoint. This complicates the use of such splay trees in a multi-threaded environment. The analysis of pairing heaps' time complexity was initially inspired by that of splay trees. The splay tree was invented by Daniel Sleator and Robert Tarjan in 1985.
