Re: Bone Marrow Preserved in 10 mya Fossil
Bad taste in my mouth here. Thuuuuph thzzzz..... If the original
color of the bone marrow (The soft, fatty, vascular tissue that fills
most bone cavities and is the source of red blood cells and many
white blood cells.) is still visible and the material is essentially
unchanged, it may indeed technically be fossilized (Def: All the
processes that involve the burial of a plant or animal in sediment
and the eventual preservation of all, part, or a trace of it.) I
think however it is stretching the usage being preserved without
replacement or substitution of the original material by some process
other than isolation from degrading influences. Apparently these were
preserved in a non-permeable, oxygen free, bacterial free
environment. Extrapolating metaphorically,..... a bone buried a week
by a flood and then dug up is a fossil. My question is, is the stuff
just dried out and thusly preserved for 10 million years or is it in
fact "fossilized" ? Opinion? Maybe I am just splitting hairs with a
I can see the discussion of resurrected fossil stem cells now to
regenerate a missing fossil appendage. If a piece of the fossil is
missing, just grow it back.

Fossilized bone marrow has been discovered in ten-million-year-old
frogs and salamanders from an ancient lake bed in Spain, scientists
The specimens are the first examples of fossilized bone marrow ever
to be discovered. They are so well preserved that the original
color of the tissue is still visible.
An international team of paleontologists, spearheaded by Maria
McNamara of Ireland's University College Dublin, made the find
while studying the remains of more than a hundred ancient frogs and
The discovery suggests that many other fossil bones may contain
well-preserved remnants of bone marrow, the scientists say.
"The marrow is organically preserved," McNamara said. "The original
color of the marrow is preserved."
The finding is "very interesting," said John Horner, curator of
paleontology at Montana State University's Museum of the Rockies in
The next step, McNamara says, is to determine what the fossilized
marrow is made of.
"We have started the analysis, but we're not finished," she said.
The fact that part of the marrow is red, however, makes it likely
that it carries some of the original biological materials, such as
remnants of hemoglobin, the oxygen-carrying substance that gives
blood cells their color.
