Are Libocedrus and Helianthus both types of plants?
Helianthus Helianthus or sunflower (from the Greek: ήλιος , "Hēlios", "sun" and ανθός , "anthos", "flower") L. is a genus of plants comprising about 70 species in the family Asteraceae. The genus is one of many in the Asteraceae that are known as sunflowers. Except for three species in South America, all "Helianthus" species are native to North America. The common name, "sunflower", typically refers to the popular annual species "Helianthus annuus", or the common sunflower, whose round flower heads in combination with the ligules look like the sun. This and other species, notably Jerusalem artichoke ("H. tuberosus"), are cultivated in temperate regions and some tropical regions as food crops for humans, cattle, poultry and ornamental plants. The largest sunflower field is located in Tuscany, Italy.
Liopleurodon Liopleurodon ( ; meaning 'smooth-sided teeth') is a genus of large, carnivorous marine reptile belonging to the Pliosauroidea, a clade of short-necked plesiosaurs. The two species of "Liopleurodon" lived during the Callovian stage of the Middle Jurassic Period (c. 160 to 155 mya). It was the apex predator of the Middle to Late Jurassic seas that covered Europe. The largest species, "L. ferox", is estimated to have grown up to 6.39 m in length.
