Boreholes in the fossilized bones of ancient birds are hinting that Osedaxa genus of worms that feeds on whale bones, Würmer aßen on the bones of birds long before it tackled Würmer aßen in whales.

The research, reported online in the journal Naturwissenschaften 1targets the fossil remains of two penguin-like birds from the family Plotopteridae that were flightless Würmer aßen probably survived was ging ich Würmer diving for fish in marine environments.

At around 30 million years old, the bones are heavily corroded with age and show scrape marks that were click the following article made check this out scavenging sharks after the birds died.

Even so, boreholes can be seen in all of the bones. The animal that produced read more boreholes had a branching 'root Würmer aßen that grew to a length of at least 3 millimetres. Most of the holes have a diameter of no more than 0. X-ray computed tomography scans of the bones show that Würmer aßen holes lead into Würmer aßen network of cavities inside the fossil bones.

All of Würmer aßen click here make the holes look very much like those that are made in whale bones by modern Osedax species. The discovery changes perspectives on what these worms are able to eat. To date, experiments show that Osedax species can feed on bones from elephant seals, cows and whales, continue reading they have not been reported to eat bird, reptile or fish bones.

For this reason alone, the Würmer aßen of Osedax boreholes in bird bones is remarkable because Würmer aßen suggests that these worms once had a wider diet.

But there Würmer aßen much more to the learn more here than an expanded historic feeding regime. Based on palaentological estimates, Osedax worms might Würmer aßen followed two possible evolutionary paths, explains Vrijenhoek. They could have evolved alongside whales roughly 30 million to 40 million years ago during the Paleogene period, or they could have evolved 70 million to 80 million years ago during the Cretaceous.

Until now, the discovery of Paleogene fossil whale bones with boreholes in them — and the fact Würmer aßen no other marine fossil had Würmer aßen found to contain boreholes — hinted that the worms evolved to feed on whale bones in step with the evolution of marine mammals. By contrast, a Cretaceous evolutionary Würmer aßen seemed a dim possibility, as no marine mammals existed that long ago, and modern observations have shown that the worms feed only on mammal bones.

The discovery of bird bones with boreholes changes this because it suggests that Würmer aßen worms have not been limited to a diet of mammal bones throughout their Würmer aßen. One problem with the theory that the worms evolved during the Cretaceous period and fed on the large marine reptiles of the time Würmer aßen that they would not Würmer aßen had much food after Würmer aßen Cretaceous—Tertiary extinction that took place 65 million Würmer aßen ago and wiped out all large reptiles.

I hadn't even considered the possibility of diving birds. Würmer aßen is a truly novel Würmer aßen. Marine birds have existed continuously since the Cretaceous, and so would provide an Würmer aßen food source for Osedax.

However, the discovery does not resolve all of the evolutionary questions surrounding Check this out. To further Würmer aßen the theory that the worms evolved during the Cretaceous, scientists will need to find evidence of large marine reptile bones containing boreholes.

I'd really like to get a systematic search going," says Kiel.
