procumbent

"Somewhat unexpectedly, both pairs of premaxillary teeth project anteriorly and laterally at the base, implying a procumbent nature atypical of tylosaurines," the study reads.

Fruit dry, twin, of 2 indehiscent 1-seeded carpels.—A slender procumbent herb, with square stems, lanceolate pungent leaves in whorls of 4–6, and small subsessile blue or pinkish flowers surrounded by a gamophyllous involucre.

Incisors not rooted but continuously growing; those of the upper jaw curved and directed downwards; those of the lower straight and procumbent.

Skull: Larger in every measurement taken; premaxillae extended farther posteriorly to nasals; extension of supraoccipital posterior to lambdoidal suture markedly less; tympanic bullae actually as well as relatively smaller; upper incisors longer and more procumbent.

Leaves.—Mostly alternate on the flowering stems, but smaller and broader ones often opposite or whorled on the procumbent shoots; linear; smooth.
