We report the discovery for the first time of fossilised diatoms in a carbonaceous meteorite that fell in the North Central Province of Sri Lanka on 29 December 2012. Contamination is excluded by the circumstance that the elemental abundances within the structures match closely with those of the surrounding matrix. There is also evidence of structures morphologically similar to red rain cells that may have contributed to the episode of red rain that followed withing days of the meteorite fall. The new data on fossil diatoms provide strong evidence to support the theory of cometary panspermia.
Fragments of the meteorite were examined under an environmental scanning electron microscope at the School of Earth Sciences at Cardiff University. Structures of various shapes, including large numbers of slender cylinders of lengths 5-10µm, and a few micrometers in diameter are seen to be distributed extensively throughout the sample. The larger ovoidal object possesses a micro-structure and morphology characteristic of a wide class of terrestrial diatoms. Diatoms are unicellular phytoplankton. The intricately woven micro-structure of these frustules would be impossible to generate abiotically, so the presence of structures of this kind in any extraterrestrial setting could be construed as unequivocal proof of biology.

My last comment is the lead researcher Professor Chandra is controversial. He's widely known for his panspermia theory and his buddhist beliefs that influence his research. Take with some salt. When this is peer reviewed, it may have some merit, or not. Until then, it's just a story.edit on 14-1-2013 by jonnywhite because: (no reason given)
We conclude by reporting that an extract from the interior of a Polonnaruwa meteorite sample, studied under a light microscope at the Medical Research Institute in Colombo, was found to contain living diatoms (See Fig.4). If this result is confirmed in future studies and contamination is excluded, the meteorite would have been shown to contain both fossil as well as living microbes, and panspermia thus demonstrated in real time.

The figure shows a live diatom claimed to be extracted. This would be really cool if it turns out true.

Reliability
The quality of peer review at the journal has been questioned several times.[2][3][4][5] The journal has also been accused of promoting fringe viewpoints and speculative viewpoints on astrobiology, astrophysics, and quantum physics. Skeptical blogger and biologist PZ Myers said of the journal "... it isn't a real science journal at all, but is the... website of a small group... obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down on Earth."[
I think you are correct! Although there may be ealier photographs of such Diotoms or Bactirium in carbonaceous chondrites. Perhaps this will be the first to be proven as a fossil of a once living organism that fell from space on a meteorite, i.e. first image of a real ET!
If the picture is what its claimed it is then I guess that the first picture of an ET on ATS
How do you suppose a meteorite could be contaminated with fossils? These fossils appear to be imbedded in the carbonaceous chondrite. Diatoms are marine organisms and fossilization takes some time. This meteorite apparently was found within hours, or days, after it hit the ground.
I suppose the hardest thing to prove would be lack of contamination.
So red rain fell at around the same time as this meteorite. Has this red rain been found to be a HOAX or terrestrial in origin, or could this be the unfossilized or even living organisms of the same type that have been found within this meteorite?
A remarkable coincidence that should be noted is that within several days of the meteorite fall, an extensive region around the site of the fall experienced an episode of red rain. The red rain analysed at the MRI in Colorado has been shown to contain red biological cells that show viability as well as motility.

It is possible that the fossils originated on Earth.
The meteorite may have been a chunk of rock thrown into orbit by an asteroid striking Earth long ago. If this is the case, the fossils are not extraterrestrial.
We are told that the Martian meteorite was dislodged from Mars the same way.

Yeah not the best for sources and I am highly doubtful but we can hope.

Abnormally high abundances of As(Arsenic) and Ag (gold) in the Sri Lankan red rain cells have been provisionally reported, thus favouring a non-terrestrial habitat, possibly connected with a cometary/asteroidal body, the fragmentationof which led to the Polonnaruwa meteorite fall (Samaranayake and Wickramasinghe, 2012).
