Tallest tree was under 500 feet.
Would have to revise tree physiology to get over 500 feet.
They could stay under 152 meters and became wider - short wide trees.

Yes and browse for animals is not just trees. Sauropods would be the only thing that could reach that high and they would eat anything on the ground as well.
The thing is these trees need to be large and tall, if a half dozen brachiosaurus' ate off a single tree its got to be large and tall to withstand that kind of assault or that tree species would die out fast...The trees must be taller than any dinosaur and large enough to handle many dinosaurs routinely eating its foliage...

But none of them were miles high. 1,000 feet maybe at max.

So now this isn't to be combative. I'm asking why you think what you do, and making some suggestions based on what I would use to reason this out, which is all speculation anyways.
Why would you conclude that they couldn't be over a 1,00 feet high? See the way to defend your claim (in my opinion) would be to do the math, and since I'm doing this it's almost sure to be incorrect, but never mind that, so for example one might figure out what the gravity was at say 1/4 the mass of our present size, and this way you can take gravity which decreases by the cube to mass and apply that to locate the point where space began. At that point there would be a reasonable argument to say these trees couldn't grow any taller because they would start to become exposed to the energies from space and the cold of space.
Alternatively, a quick and dirty estimation might be to simply use one of these stat's to get a ruff idea how high space might have been. (see if I can hide this from Morrison's eyes).
Gravity falls by the cube. I'm certainly not qualified to figure this out but off hand I'd make a guess that a planet 1/4 our present size would then have a gravitational field 1/16th that of our present gravity. So 380.000 feet / 16 gives a figure of 23.750 feet. A reasonable height then might be expected to be around 18 times that of your estimate. However what the weather would be like on such a planet is unknown to me. You would expect there to be almost no wind like the moon.
I just don't see a logic to the notion that there's a limit to their size. A more logical approach than the aforementioned would use some estimates based on the integrity of the trees' biology in a gravitational field that's 1/16 that of our present field. This is going to give us a fair idea of how much weight the base of the bio matter could support.
Another angle might be to explain what prevents trees from growing taller today? Does anyone know why? Has anyone ever thought or written on this before?
General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet.
"Low Earth Orbit" (LEO), where many satellites live, goes from 160km (100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5 million feet).
Starting above the 'space' limit but a bit before LEO, the inner Van Allen Belts, which magnetically shield the Earth's surface from high energy particles, extend from 100km (62 miles, 33,000 feet) up to 10,000km (6,200 mil, 3.3 million feet).
How High Up Is Space?

You haven't meet Mr. Darkness, that is his personality.
lol. ok? So you stopped casually standing by for a jab?
Nah, I was sticking up for you.
Besides I like the dark.

A petrified forest was discovered in Texas in 1927 situated in a virtually inaccessible valley of the Big Bend with stumps of trees 100 to 150 feet high and trunks of petrified trees over 900 feet long.
You do know this is bunk don't you?
The trees were "Giant Sequoias".
Texas Tall Tale - Graham Hancock Official Website
Sequoias only grow in California. In the Sierra Nevada Mountains (Redwoods grow along the Northern coast), where it gets 40+ inches of rain a year.
Big Bend is on the Texas-Mexico border.
”Over 50 logs are exposed in the Paleocene Black Peaks Formation in the Tornillo Flats region of the Park, west of Texas state highway 385. More than 40 logs are over 1 m in diameter; the largest log is 2.4 m in diameter and over 10 m long...”
Much smaller than your source is claiming.
In fact the 1927 article that is the basis for the claim reads like satire.
