Dinosaur - In the Footsteps of Dinos

Dinosaurs - Colorful Creatures?

The word dinosaur might make you picture large green beasts, but that's just the work of artists and your imagination. The truth is that nobody really knows what color dinosaurs were. These guys have been buried for over 200,000 years and you can't tell what color they were from fossils. Palaeontologists (scientist who study dinosaurs) believe dinosaurs were probably earth-tone colors - green, gray, brown - just like reptiles today, so they would blend into their environment.

Dinosaurs - The Name Game

Most dinosaur names aren't as easy to say as T-Rex. Try saying these names out loud: Procompsognathus, Tuojiangosaurus, Archaeopteryx. Dino names usually combine Latin or Greek words, which often describe the dinosaur. Triceratops means 'three-horned face'. Other times they are named after the place they were discovered like Arctosaurus found near the Arctic Circle. Yaleosaurus was named for Yale University. Some dinosaurs are even named for people. Palaeontologist Orthneil C. Marsh had Marshosaurus named after him. About 700 species have been named. That's a tough list to memorize.

Dinosaurs - Beginning to End

The years dinos roamed Earth are divided into three periods, which are called the Mesozoic Era.

  • Triassic Period (225 to 193 million years ago) - During the Triassic Period, dinosaur ancestors were evolving. In the Late Triassic, the world saw the first true dinosaurs.
  • Jurassic Period (193 to 136 million years ago) - In the Jurassic Period, the number of dinosaurs grew.
  • Cretaceous Period (136 to 65 million years ago) - By the Cretaceous Period, many different types of dinosaurs had evolved.

Dinosaurs - Bon Voyage

Scientist know dinosaurs were no longer around 65 millions years ago. They can tell how old layers of rock are and no dinosaur bones have been found in rock less than 65 million years old. So how did they all die out? There are two main theories about this:

  • Gradualistic theories say the dinosaurs were in a slow decline and that gradual changes in the environment caused their extinction.
  • Catastrophic theories say the dinosaurs disappeared abruptly due to some world-wide catastrophe. Perhaps a giant meteor crashed into Earth, covering the world in dust and hiding the warmth from the Sun.

Dinosaur Fun Facts

I originally got this story from a source that most people wouldn't exactly call credible , a comedy/politics TV show, but after checking their sources, I believe I have a strong case with decently strong sources. You are incorrect when you said you'd only have to pay for labor and materials, as several other factors come into play. Also, where I said 1000 feet, I very much apologize, more like 1000 miles. It should cost about 10 billion for the concrete panels, and although concrete is cheap, it's not dirt cheap, and 1000 miles of concrete will add up to a pretty good amount. Next it should cost 5-6 billion dollars for steel columns to hold the panels, including labor.  Add another billion for concrete footing and foundations, and that's sixteen billion dollars. But, transport is required to inaccessible areas. It will cost about another 2 billion dollars to build roads that will allow 20 ton trucks to carry materials to the wall. We also need engineering, design, and management, which brings us up to the magic number of 25 billion dollars, on average considering all factors. The Congressional Budget office also says that wall management costs will exceed the original cost to build the wall in as little as seven years. With the Mexico paying for it part, as John Oliver, the host of this show, says, "People don't exactly love it when you make them pay for [expletive] they don't want." The current Mexican treasury secretary states, "Mexico, under no circumstance, is going to pay for the wall that Mr. Trump is proposing." 2 former Mexican presidents that only recently left office also say, in a nutshell, that Mexico will never pay for the wall.

I'll have to dig into that a little more, I only had about 2 sources to go off of, one of them being a private party. I am aware that scientific or economic articles aren't always correct, so I'll have to fact check this myself before I can properly reply to you.

I'd say it's a good idea, but I don't think the economist is correct. Firstly, even if he were correct, the price of the wall only comes to about half the annual trade deficit that we have with Mexico. If Mexico is making 58 billion off of us every year, then they have 25 billion to spare to pay for the wall.  But more to the point, I don't think it'll cost that much. What you'll need is money to pay for two things:  1. Materials 2. Labor You need 1.5 billion pounds worth of pre-made concrete slabs installed to create the entire wall. Concrete is ridiculously cheap, and you'd only be out three billion on concrete. Then you need steel connections between each slab, so let's add another five billion for that. Let's also add a billion dollar safe fund, in case some parts of the wall need a little something extra.  That leaves you with eleven billion dollars worth of labor before you get anywhere near the price that this economist came up with. Which is why I think he's very mistaken.

Before we start this, I have two requests. 1. Be civil to each other, rebuttal other people's statements with facts, not just random insults. I have seen debates where people are just mindlessly bullying each other, and I would hate for this to turn up like that. 2. Don't go against Donald Trump on this topic just because you think he's a racist or something. Focus on the topic at hand, please. So, we've all heard about the infamous wall. However, I have one reason that the wall might not be such a wonderful idea. Donald Trump has said that the wall will be at mimimum 35 feet tall, and again, at minimum,  1000 feet long.  Now, an economist estimated that this will cost 25 billion dollars, including costs to transport supplies, the materials, and labor, along with several other costs. This exceeds what Donald Trump says the wall would cost by 13 to 21 billion dollars. Do you still think the wall is a good idea, and remember the two requests, or no, I'd rather call them rules, I listed about a paragraph ago.
