A person who has been employed for a long time by a corporation, university, or organization. Generally used disparagingly by younger persons who regard this person as a general obstacle to progress, or one to their own personal advancement. The expression implies obsolescence on the part of the person so described, whether factually or not.
The English Department was filled with dinosaurs who were on the faculty for more than thirty years. They should set a maximum limit on the number of years a person may be on the faculty!

the word "Dinosaur" is slang for Heroin...

(not the syringe and not the "a band or belt that one would use to make their veins more visible")

Calling heroin the "dinosaur" came from an earlier slang used for Heroin "Tar". It's a common belief that dinosaurs became fosil fuel or "tar-like" over millions of years... The La Brea tar pits (in Los Angeles, CA) is an example.

The other slang contributing to the use of the "Dinosaur" meaning heroin is the saying "monkey on your back" referring to any addiction controlling you.

In the song Pool Shark by sublime Brad sings "tying on the Dinosaur tonight. ...use to be so cool."

Here he is referring to how his recreational heroin habit had grown into a full blown uncontrollable addiction. Describing his "monkey" as a "dinosaur" he had on his back can be interpreted many ways.
Brad was acknowledging the enormity of his problem, his increasing consumption, his inability to control it and also acknowledging the fact that all heroin addicts face extinction every time they get high... extinct ...like a dinosaur.
Tragically poetic!

The "tying on" or "tying off" is slang for the process of finding a vein to shoot up or more so ...the complete ritual of shooting up any drug to get high... but I digress.
I'm gonna shoot that "dinosaur" tonight.

Lyrics from "Pool Shark" by Sublime

"I like lying naked in my bedroom
Tying on that dinosaur tonight
It used to be so cool...
But, now I got that needle and I can shake
but I can't breathe.
You take it away but, I want more and more
One day I'm gonna lose the war."
-Brad Nowells (1968–1996)

The dinosaurs could have died out from a meteor or an ice age. but the real reason they died out was from having to much oral sex. this period of time was called the felacious period. dinosaurs would engage in oral sex at every oppurtune moment, instead of having regular sex to continue the population. it wasnt all in the same species sometimes the larger dinosaurs would be plaesured by the smaller ones in what was known as 'interacial hardcore midget gangbangs'. This theory is supported by all the dinosaur skelotons that have been found in the 69 position and also why there are no dinosaurs left today. the mating call most commonly used by dinosaurs was "do you want a blow job?" the reply to this was normally "yes, you bitch"
tyranosauros with a diplodocous (thunder lizard) engaging in oral sex, tricerotops asks "can i join to?" orgy insues, dinosaur orgy that is

a now extinct creature that had once walked the planet. scientists have theorys of how they became extinct.

emo//scene kids usually like this animal && call it a "dino".
they will use it as a name on their myspace or screen name.
they will have cartoon pictures of dinosaurs on their myspace also.

personally, its my favorite animal, along with the giraffe. :
dinosaurs:
tyranosaurus rex
stego saurus
brontosaurus
triceratops

an emo//scene kid may combine a type of dino saur and "rex"
e.g. brontosaurus rex;; stegosaurus rex;; etc.

Extinct creature that used to terrorize the prehistoric land, and now terrorize the hearts of modern people.
The ride became more frightening with the appearance of the dinosaur.
