Details:

Odontopteryx False Toothed Bird Bone 510mm overall on the original fossil matrix or limestone bedrock. The Tibiotarsus leg bone prepared and cleaned making an exceptional display of the prehistoric pelagic toothless or false tooth bird. The bones of the odontopteryx were fine and slight to enable flight and this bone is no exceptional to those evolved parameters. An excellent collection addition of prehistoric fossils birds or Ornithology oficianados. The fossilised bone has been cleaned, prepared and stabilised in a British Laboratory to a high standard. Because of its exceptional length this is probably part of the anatomy of a wing.
This specimen long bone illustrated shows very well the wall of the thinned (for flight) bone and the medullary cavity within, 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.

Odontopteryx False Toothed Bird Bone 510mm long and of the expected thin walled anatomical structure to the extraordinarily long mature individuals Tibiotarsus fossil leg bone. The Pelagornithidae birds which were toothless pelagic birds of the Palaeocene and Eocene of Morocco. The flying toothless bird had the appearance of teeth in its beak or jaws, giving a Pterosaur appearance at first hand when discovering the skeletal remains in the fossil record. 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 tooth like structures appear along the outer edge of the birds jaws and were not very strong, prone to breaking and quickly worn down. 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 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.
