The word "duckbill" is usable in written English and is well written.
It can be used to describe a specific type of animal, particularly the platypus, or to refer to objects that have a similar shape. Example: "The duckbill platypus is one of the few mammals that lay eggs." Alternatives include "platypus" or "bill-shaped."
More expensive "duckbill" designs that protrude from the face work better.
Platypus (Ornithorhynchus anatinus), also called duckbill, a small amphibious Australian mammal noted for its odd combination of primitive features and special adaptations, especially the flat, almost comical bill that early observers thought was that of a duck sewn onto the body of a mammal.
In the duckbill platypus, a brief courtship involving a chase in the water precedes copulation.
No lice have been taken from the platypus (duckbill) or from anteaters and armadillos, and none are known from bats or whales.
One of the most remarkable mammalian hairs is that of the Australian duckbill, or platypus, where the lower portion of the shaft is slender and woollike, while the free end terminates as a flattened, spear-shaped, pigmented hair with broad imbricate scales.
Leidy is perhaps best known for his study and description of the first dinosaur skeleton to be recognized in North America, that of a duckbill, or hadrosaur, found at Haddonfield, New Jersey, in 1858, which he named Hadrosaurus foulkii.
It has recently gone viral (currently nudging 2m hits), probably because it's the go-to facial pose on Instagram and the red carpet, usurping 2013's sleeper hit "the sparrowface" (eyes wide and mouth slightly open, like you're about to eat a worm), model favourite "the smize" (smiling with your eyes) and the wildly popular "duckface" (pouting your lips to duckbill-like proportions).
He has also been able to show, again by comparison with modern birds, which dinosaurs were up and running as soon as they hatched, and which stayed in the nest waiting for their parents to come and feed them.Furthermore, the bones of some dinosaur hatchlings, notably the duckbills, were actually made largely of cartilage, like those of nest-bound birds.
The first such bones were unearthed near Choteau, Montana, and thereafter Horner and his crews discovered hundreds of nests, eggs, and newly hatched dinosaurs (mostly duckbills).
The toes of all but the most basal ornithopods terminated in broad, almost hooflike bones, especially in the duckbills, as opposed to the sharp claws of theropods, and this is one way to distinguish their footprints.
In the last two decades, several assemblages of ceratopsians and duckbills containing thousands of individuals have been found.
