FOSSIL DIATOMS IN A NEW CARBONACEOUS
METEORITE

Buckingham Centre for Astrobiology, University of Buckingham, Buckingham, UK
School of Mathematics, Cardiff University, Cardiff, UK
Medical Research Institute, Colombo, Sri Lanka

We report the discovery for the first time of diatom frustules 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 within days of the meteorite fall. The new data on “fossil” diatoms provide
strong evidence to support the theory of cometary panspermia.


1. The Polonnaruwa meteorite
Minutes after a large fireball was seen by a large number of people in the skies over Sri
Lanka on 29 December 2012, a large meteorite disintegrated and fell in the village of
Araganwila, which is located a few miles away from the historic ancient city of Polonnaruwa.
Fig 1a shows the location of the fall. Fig 1b shows a photograph of a small piece of the
meteorite that was sent by one of us (AS) for study at the Buckingham Centre for
Astrobiology and Cardiff University.

Image

The meteorite when examined under a light microscope exhibits a highly porous and
composite structure characteristic of a carbonaceous chondrite, with fine-grained olivine
aggregates connected with mineral intergrowths. A few percent carbon as revealed by EDX
analysis confirms the status of a carbonaceous meteorite. The general characteristics of the
new meteorite bear a striking similarity to those of the unusual Maribo CM chondrite that fell
over Denmark on January 17, 2009 (Haach et al, 2011), although its porosity appears to be
significantly lower. This meteorite was identified as arising from an extinct cometary
fragment in the Taurid complex associated with comet Encke. In view of the proximity of
occurrence within the calendar year between the Maribo and Polonnaruwa events we
provisionally identify the latter as arising from an extinct cometary fragment belonging to the
same Taurid complex. We shall henceforth refer to this meteorite as the Polonnaruwa CM
chondrite or the Polonnaruwa meteorite.
At the time of entry into the Earth’s atmosphere on 29 December 2012, the parent body of the
Polonnaruwa meteorite would have had most of its interior porous volume filled with water,
volatile organics and possibly viable living cells. 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 Colombo has
been shown to contain red biological cells that show viability as well as motility. Preliminary
studies from EDX analysis show that these cells are similar to the cells found in the red rain
of Kerala that fell in 2001, cells that have not yet been identified with any known terrestrial
organism (Louis and Kumar, 2006; Gangappa et al, 2010). Abnormally high abundances of
As and Ag 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 fragmentation
of which led to the Polonnaruwa meteorite fall (Samaranayake and Wickramasinghe, 2012).

2. Meteorite analysis
Fragments from a freshly cleaved interior surface of the Polonnaruwa meteorite were
mounted on aluminium stubs and examined under an environmental scanning electron
microscope at the School of Earth Sciences at Cardiff University. Images of the sample at
low magnification displayed a wide range of structures that were distributed and enmeshed
within a fine-grained matrix, of which Fig.2 is an example. EDX studies on all the larger
putative biological structures showed only minor differentials in elemental abundances
between the structures themselves and the surrounding material, implying that the larger
objects represent microfossils rather than living or recently living cells. For the smallest
structures, however, such a distinction could not be easily made from EDX studies alone.
Other criteria will be required.
The donut-shaped structure seen in the bottom left corner of Fig.2 is one of many that were
found in the Polonnaruwa meteorite that bears a striking similarity to the SEM images of the
Kerala red rain cells (Louis and Kumar, 2004; Gangappa et al, 2010). We discuss elsewhere
the possible link between these structures and the red rain that followed the meteorite fall.

Image

Other structures of various shapes, including large numbers of slender cylinders of lengths 5 -
10μm, and a few micrometres in diameter are seen to be distributed extensively throughout
the sample. It is of interest to note that precisely such types of dielectric particles, which may
have a pre-solar origin, have been invoked to explain both the linear and circular polarization
of starlight (Wickramasinghe, 1967). As early as 1976 the presence of clumps of biogenic
material in carbonaceous chondrites was inferred from spectroscopic studies at ultraviolet
wavelengths (Hoyle and Wickramasinghe, 1976). The identification of infrared spectroscopic
features of interstellar and cometary dust with the spectra of diatoms has also been discussed
(Hoover, Hoyle, Wickramasinghe et al 1986). The discovery of diatoms in a carbonaceous
chondrite therefore comes as no surprise.
The larger ovoidal object in Fig 2 possesses a microstructure and morphology characteristic
of a wide class of terrestrial diatoms. Diatoms are unicellular phytoplankton characterised by
elaborately sculptured frustules comprised of a hydrated silicon dioxide polymer. The
intricately woven microstructure 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. Diatom fossils of a wide range of types are found
marine sediments dating back to the Cretaceous Tertiary boundary 65 million years ago.

In the higher resolution image of Fig3 we can unambiguously identify an object as being a
diatom from its complex and highly ordered microstructure and morphology, a structure that
cannot result from any conceivable mineralisation or crystallisation process. The mineralised
fossil structure of the original diatom has been preserved intact and displays close similarities
in elemental abundances with the surrounding material. This is shown in the EDX maps in
Fig.4, that compares the distribution of elements inside and outside the fossilised object.
One of the many slender cylinders seen in Fig.2 is examined under higher magnification in
Fig.5. The intricacy of the regular patterns of “holes”, ridges and indentations are again
unquestionably biological, and this is impossible to interpret rationally as arising from an
inorganic crystallisation process. Here too the near identity of elements inside and outside
the structures point to a mineralised fossil rather than a recent diatom.

I may have missed Cages thread, but nothing on it proves anything one way or the other.
However, I have sent an email to the professor with a few questions of my own...we'll see.

agreed ...but the source material and lack of any substantial publicity or follow up, doesnt bode well, however it will be interesting to see if you get a reply and what the professor has to say... :flop:

I wonder what do they have to say about this discovery :

Image

EDIT :


Ah, yes...their official opinion on alien life :

Although scores of well-educated scientists believe it—in spite of that annoying little matter of a complete lack of fossil evidence—it is obvious that evolution simply isn’t possible, let alone logical.

This is why so many scientists earnestly, often desperately, sometimes embarrassingly hold out hope that they can find life in outer space. Life on Earth coming from non-life is impossible (they would grudgingly admit only that it is “improbable”)—even when you multiply the non-existent odds by trillions of planets. In a silly modification to the theory, some think that maybe life came from dead material on some other planet, then ricocheted on over here aboard a blasted-off piece of rock.


It is a desperate, last-ditch grasping at straws. It’s not even a ridiculous theory; it’s a disproved hypothesis. But at least it offers them what they cherish more than anything else in their belief system: the chance to smugly cling to the faith that God doesn’t exist.

But as long as this deep faith in a godless existence permeates science, the Hoover-style half-baked guesswork is really not that far removed from the high-profile science at some of our society’s most respected institutions. Just like looking at a rock and seeing an alien, precluding the existence of a Creator is “science by wishful thinking.” ▪

I will be happy to forward this recent discovery to the Trumpet as well and see if their position changes.
They sure look like micro organisms to me.

Although I know Edgar was being facetious by posting a Trumpet article, I think an explanation is warranted so I sent the pdf and my questions on their take of this new discovery. When I hear back from them, I will update this thread.
