This is an interesting concept. Did this just occur to you or have you encountered this theory somewhere? I'd like to read more...
Actually, most hard-core paleantologists tend to imagine that they are in fact witnissing dinosaurs in their daily lives when they interact with birds. They cream their pants over this stuff.
It's a fairly well-accepted principle of evolution. Richard Dawkins, the noted evolutionist, calls the separation of the continuum of life into species "the tyranny of the discontinuous mind". Whenever anyone attempts to make a distinction between "microevolution" and "macroevolution" they are exhibiting this flaw in common thought. We only divide animals into species because the practice dates back before evolutionary theory, and if there's one thing humans are bad at, it's breaking tradition.
Incidentally, there's a movement in taxonomy to completely eliminate the old system of classification and instead use molecular evidence to determine the relation of all living things to each other. I have to say I think this is a terrific idea, as it would eliminate any residual confusion that is inevitable when an entire discipline is turned on its head (as biology was when Darwin first published his theory).
If you'd like to read more about this and other enlightening evolutionary topics, I highly recommend "The Ancestor's Tale" by Dawkins. A lucid and fascinating read.
Don't worry, I'm well-versed in evolutionary theory (which is why I
don't read Dawkins. --Perhaps I am too sweeping in considering anything else written by the man who wrote "The Selfish Gene" to be tripe; but it is what made him famous...so, as his major theories propounded within that are tripe, I imagine the rest are as well)

Yeah, I hate the words "macro" and "micro" evolution. likewise "evolutionist." What no Fundie or Creationist will ever understand is that supporting Darwin's theory of natural selection in no way puts you into a club, or cult--believing in evolution does not equate to subscribing to an ideal. No evolutionary theorists use macro or micro evolution. It isn't in the legitimate literature....simply b/c, the two (if they were legitimate concepts) are the same. I like when people use words that they invent, to apply to and attack a concept they have little hope of understanding. Wait; I don't like it...I find it aggravating. It wouldn't bother me if their ignorance were self-contained; but these people try to enforce such ignorance on their own children and worse yet--other peoples' children, as if they have some infallible right to do so. I find these tactics to be extremely dangerous to the culture and economic well-being of our country...
Molecular classification seems like the way to go. Working in the molecular field, this is how we think anyways. ...I don't so much as consider different species anymore but sequences. Maybe it becomes impersonal; but it's the most accurate way to classify.
EDIT: I forgot to explain what I found interesting abotu the continuum: Yeah, that is something that isn't new to me...what I actually hadn't considered through it though, is more philosophical, really. The idea that I am still living with dinosaurs or bromeliads....Sure, I do feel a sense of awe walking through a fern forest (A really cool thing), for some reason, I never equated that recognition to the feeling. Tom's statement drove it home I guess, in that I never considered such an elegant connection to the past.
I love the idea of our cells (and us) only existing b/c of ancient prokaryotic invasion/engulfment. Sure, it's not the most well-supported theory in evolution, but it makes
sense. While this has always fascinated me...I never considered it on a grander scale. Cool stuff. I have Gould's Opus; but I haven't attempted to crack it's 1600 pages. I stick to his other stuff...
