It is a fact that when someone
refers to another person as a ‘dinosaur’ then what they are alluding to are
qualities synonymous with being slow, obsolete, and even close to extinction.
It is rarely meant as a compliment except when used by people who are actually
interested in dinosaurs.
Guess what? I am interested in
dinosaurs!
I have been fascinated by these
animals ever since I received a book on them for my birthday when I was a
child. This one in fact:
Reading this book for the first
time proved a watershed moment. I wanted to be a Palaeontologist from that
moment on. Unfortunately my academic abilities never allowed me to achieve that
particular dream as a profession; my mathematics is very weak despite several attempts
to improve it. I did, however, become something of an amateur Palaeontologist
and I remain so to this day.
When the above book was published
dinosaurs were seen as nothing more than big lizards that spent all morning sat
in the sun until they got warm enough to move. Once they reached an optimal
temperature then they would set off and do dinosaur things, like eating each
other, before night came and they had to sit down again as the lack of sunlight
placed them back in a kind of torpor.
Then this book came along in
1986:
Dr Robert T. Bakker was and still
is the enfant terrible, of
Palaeontology. He looked at dinosaurs with young eyes and was certain that we
had gotten them wrong. ‘The Dinosaur Heresies’ is so named because it attacks
the extant theories of dinosaurs modelled as giant reptiles that had persisted
unchallenged for decades. Inspired by his mentor John Ostrom Bakker used his
considerable talents as an artist to redraw dinosaurs as active animals more
alike to mammals in terms of physiology and appearance than they were to
lizards. He supported his dynamic representations with a considerable amount of
science presented to less well educated readers like myself in a very
accessible fashion, or ‘popularist’ as some of his critics would term it.
This new representation of
dinosaurs was one of very active animals that lived more like the warm-bloodied
(endothermic) mammals that the cold-bloodied (ectothermic) reptiles. They did
not lumber anymore but ran with agility and speed.
Instead of the sprawled reptilian
pose favoured for the reconstruction of skeletons Bakker suggested something
much more revolutionary. The drooping tail was lifted from the floor and the
animal became something far more effective in the process.
Deinonychus was discovered by
John Ostrom and its reconstruction as an active predator was contentious at the
time but it was the only one that explained the animal’s sickle shaped claws that
armed its feet.
This was not a slow moving,
obsolete, dullard of a creature. Clearly Deinonychus possessed traits that were
more commonly seen in mammals. It was swift, powerful, agile and intelligent.
This was an animal that evolved to meet changing demands of both its
environment and its ecological niche. It was superbly adapted to carry out its
role as a small to middle sized predator.
Of course, as someone with a
passionate interest in Palaeontology and dinosaurs in particular I appreciate
all of the facts above. Dinosaurs were the supreme forms of life for over 231
million years whereas mammals only really came to prominence less than 65
million years ago. It was only the extinction event that killed the dinosaurs
that actually allowed mammals and birds, the only dinosaurs to survive, to rise
to their position of supremacy.
So for me being termed a
‘dinosaur’ is actually a compliment not a criticism. I would dearly love to be
as successful as these fabulous creatures were. I’d like to be around for as
long as them as well but that is another matter!
