And, some might say, ethics: 'golden tabby tigers' are beautiful bengal
x siberian tiger hybrids. Like manx cats, they are prone to deformities
of the lumbar vertebrae and pelvis and often have a peculiar gait. Zoos
nowadays try to keep their 'subspecies' pure but this was certainly not
the case in the recent past.
Curiously enough, this message came in just when I was putting the
finishing touches to a news article about the remarkable
_Lissodelphis_-_Lagenorhynchus_ hybrid recently photographed in the

It died on its first day.
_DINO PRESS 5_
Recently received my copy of _Dino Press_ 5. Congrats as always to
Masaaki Inoue and the team, it's excellent and a fun read. Funny
coincidence that Ralph Molnar should discuss _Dandakosaurus (albeit
briefly) not long after it was mentioned here on DML (though why no
mention of the idea that it's an abelisaur, or that _Sigilmassasaurus_ is
a synonym of _Carcharodontosaurus_?).
George's BCF article: I liked Tracy's little drawings (except the
arrows), but I think the pics in Fig. 3 and 4 are the wrong way round.
Surely Fig. 3 should be the one that shows 'dino-birds' evolving
separately from ground-bound archosaurs, and Fig. 4 should be the one
that shows multiple terrestrial lineages evolving from the dino-birds.
And nice to see _Eotyrannus_ make the cover...
