Not dinosaurian, but interesting nonetheless.
The 5,000 DNA letters spell out the genetic code of its mitochondria, the
structures in the cell that generate energy. [snip]
Some 46 chunks of DNA sequence were matched up and arranged in order,
giving a complete record of the mammoth's mitochondrial DNA - the circular
scrap of genetic material found outside the cell's nucleus.
Mammalian mitochondrial genomes are typically closer to 17,000 nucleotides
long, as in most vertebrates. 5,000 is less than a third - though arguably
just as good as the whole mitochondrial genome for determining the mammoth's
