Odontopteryx Bird Bone 215mm of long thin walled anatomical construction, an Ulna or Radius wing bone. The Pelagornithidae birds which are toothless pelagic birds of the Palaeocene and Eocene of Morocco. Actually this thin walled bony flying toothless bird, also referred to as the pseudo tooth, bony tooth and so on, had the appearance of teeth in its beak or jaws, giving it a Pterosaur appearance, at first hand when discovering the skeletal remains in the fossil bed. The teeth looking structures were in fact a anatomical feature termed Volkmann’s canals, in the simplest terms Volkmann's canals are any small channels within bone that transmit blood vessels. These atomic cortical bone structures appear along the outer edge of the birds jaws and were not very strong, Unlike teeth of dentin these arrangements were more adapted to holding soft bodied creatures like cephalopods or fish which enabled the toothless birds to grasp and immediately swallow prey.
The specimen long bone illustrated shows well the wall of the thinned for flight bone and the medullary cavity, where perhaps the spongey marrow would form, however this is not yet clear from the fossil remains found to date and may never be positively identified. A great example which gives a good opportunity to study closely the pseudo tooth's anatomy.
The odontopteryx ranged globally and may not have returned to its birthplace but only to reproduce, having a lifestyle similar of the great Albatross of today. Having very fine or hollow bone structures to enable flight, the downside to this was the light construction which may not have normally supported strenuous activity such as diving into the ocean for prey as is quite often depicted, rather to scoop its prey from the surface or just under the surface, its beak being the only part of its body to feel the full force of flight while skimming across the sea.
The enigmatic Pelagornithidae birds narrowly missed early man on earth, Homo habilis 2.6 million years, Pelagornithidae birds show up in the fossil record from the Palaeocene to the end of the Pliocene a reign of about 50 million years. In the Palaeocene fossils have been found of a size of the great Albatross around 3.5 metres wingspans. It is estimated the largest of the Pelagornithidae attained a size of about 5 to 6 metres, with the ability to fly rather than soar, as at one time science thought Pterosaurs did only soar, today new research is leaning away from those theories for Pterosaurs. The great Pelagornithidae birds must have dominated the ocean scene in great numbers, ranging over much of the planet.
These remains are from a classic fossil bed site in what is now the Middle Atlas of Morocco, North Africa. As the machinery of the largest industry of Morocco near casablanca, rolls forward it exhumes thousands of tons of phosphates rock for the production of cement, these fossil bones are dredged up as a by product. If not foraged immediately they become crushed in the automated machinery along with all other phosphate mineral material.
The pelagic birds (a bird that spends a significant portion of its life on the open ocean, rarely venturing to land except to breed), had therefore a vast range and are found from South America to North Africa. However their remains are very scarce, perhaps due to the lightweight frame of birds generally, their bones were easily dispersed and broken down rather than fossilising successfully in sediments.
