The description sounds like elements of both the book series and the filmed version
Society of sentient dinosaurs
Dinotopia is a fictional utopia created by the artist and writer James
Gurney. It is the setting for his illustrated book series about an
island inhabited by humans and sentient dinosaurs who have formed a
complex, interdependent society.
Steam punk elements
The Dragoncopter was an experimental aircraft designed and built by
Arthur Denison. It was a steam-powered ornithopter built to resemble a
dragonfly. The engine also used kerosene in some capacity. The machine
was primarily a glider; the engine was only capable of providing five
minutes of powered flight.
Crystals (note: appears to only be prominent in the filmed version)
Sunstones are the power-source of Dinotopia. They provide protection
to the island by amending a high-pitched sound when placed in a
sunstone holder that keep the Carnivores inside the Rainy Basin and
the Pteranodons in the lower half of Canyon City. All towns and cities
own a sunstone for protection in the miniseries and tv series.
