Well, spring is here and
winter is finally over! Isn't it great! Here in Utah, we don't have a
whole lot of seasonal changes, but we have been experiencing dogwoods
and other trees in bloom. Their very beautiful this time of year.
Anyway, let's get started with our “usuals”.

In the Spotlight
Today
we've got some more terrific news from two great upcoming films:
Dolphin Tale 2 and Jurassic
World. Concerning DT2,
as many of you might know, they recently finished the production
process and have moved on to the post-production stage. On April 11,
the first trailer for the film is going to appear on television!!! I
can't wait to see it!
Just
last week, it was revealed that the Asian actor Irrfan Khan is
portraying the owner of the new Jurassic Park
in the film Jurassic World
(initially titled Jurassic Park IV).
Earlier this week, we learned some more terrific news about the film: IGN had a recent interview with the film's director Colin Trevorrow
and he not only spills some facts we never knew before about the the
new characters in the film, but he also revealed a character from the
first Jurassic Park
that will be in JW –
Dr. Henry Wu!!!
B. D. Wong is going to portray Dr. Henry Wu in Jurassic World!!! |
Dr. Henry Wu – who was portrayed by B.D. Wong –
was the head geneticist at Jurassic Park
and is one of the people responsible for bringing John Hammond's
dream to reality. Jurassic Park: The Game
(which is considered part of the Jurassic Park
film canon) reveals that Dr. Wu took over the role as head geneticist
after the former head geneticist, Dr. Laura Sorkin, disagreed to take
“short cuts” when it came to recreating the dinosaurs and was
demoted. In the first film, Dr. Wu has a very small but also very
crucial part. In the fourth film however, it appears that he'll have
a much larger part. Here is a snippet of the interview with Trevorrow
where he talks about Dr. Wu and some information about the film's new
characters:
He went into detail about Chris Pratt's character, Owen:"I know a lot of fans want to see the original characters back. They’re iconic. But I respect those actors too much to shoehorn them into this story for my own sentimental reasons. Jurassic Park isn’t about the bad luck of three people who keep getting thrown into the same situation. The only reason they’d go back to that island is if the screenwriters contrived a reason for them to go. But there is a character from the first film who makes sense in our world. This hasn’t been announced yet, but BD Wong will be returning as Dr. Henry Wu. He had a much larger role in the original novel, he was the engineer of this breakthrough in de-extinction. He spent two decades living in Hammond’s shadow, underappreciated. We think there’s more to his story."
"He’s a classic hero in a very modern context. He’s the guy who will get you through the jungle alive – but like Malcolm, Grant and Sattler, he’s an expert in a scientific field that’s connected to our story. The character allows us to explore some new ideas about our relationship with these animals, without losing the humor and sense of adventure. He’s a great contrast for Bryce Dallas Howard’s character, who starts off very corporate, very controlled. Until the running and screaming starts. Then they need each other."
I'm
really glad that Dr. Henry Wu is making a comeback and I agree with
Trevorrow's decision not to include Dr. Ian Malcolm, Dr. Alan Grant
and Dr. Ellie Sattler in the fourth film; after all, they criticized
the park! Why on earth would they be in JW's
new park if they despise it? So really, Trevorrow's decision makes a
lot of sense to me.
Topic of the Week by
Christian Ryan
In the January of 2014, scientists at the Lund University in Sweden
discovered that by looking at the melanosomes on specimens of
fossilized marine reptile skins, they've been able to tell what their
most likely skin color was in life! There were three marine reptiles
involved in this study: one was an extinct species of leatherback sea
turtle, an agile dolphin-like reptile known as an ichthyosaur, and
(my favorite of the three) a colossal sea-going lizard called the
mosasaur. Mosasaurs looked a lot like a cross between a monitor
lizard, a whale and a great white shark; some mosasaurs grew 40-50
feet in length!
The coloration of most extinct creatures has been a mystery since
coloration doesn't (normally) appear in fossils. So pretty much since
we dug up the first fossils of extinct creatures, scientists and
others have had to make educated guesses as to what colors they were.
However, this all changed a few years back; a few months ago, I wrote
an article concerning the discovery of melanosomes (those are special cells which contain the color pigment in both animals and humans) that could be seen
with a microscope on the fossils of some dinosaurs and extinct birds.
It turns out that scientists can look at the size and shape of the
melanosomes and the distance between the melanosomes to determine the
coloration of some creatures! Now, this same science is being used to
color other extinct creatures – this time creatures of the sea!
So how did the scientists determine the creatures' color? Well, first
they wanted to see whether or not the microscopic objects in question
were really melanosomes or from the result microbial contamination.
What they did was use a special technique known as “energy-dispersive
X-ray microanalysis”. In other words, they used an X-ray to test
how the sample of the specimen reacted. The scientists learned that
the objects in question were in fact associated with preserved skin
film that was found on the three fossilized creatures and not
something else. Thanks to this information, the scientists began
looking closely at the melanosomes of the three animals (which were
oval-shaped, by the way) to determine their distance apart from each
other.
Despite its appearance, ichthyosaurs, like this Ichthyosaurus, were not fish, but reptiles. |
The study revealed that the leatherback sea turtle was – like the
modern leatherback sea turtle – was probably mostly blackish on the
upper regions of its body with a paler underbelly. They found this to
be true with the mosasaur as well! The ichthyosaur was a different
story – instead of being blackish on the top and whitish on the
bottom, it seemed to be all blackish colored! (This study doesn't mean however that all species of mosasaurs or ichthyosaurs were these colors) Why did all
three of the animals have black on their bodies? Was it just
coincidence? And what was the purpose of the black coloration anyway?
Prognathodon was one of the many species of mosasaurs. |
Well, we can't say for sure, but scientists can make some educated
guesses by looking at modern animals. You might have noticed that
mosasaurs and the extinct species of leatherback sea turtle have a
similar coloration to a wide variety of modern sea animals; killer
whales, great white sharks, modern leatherbacks, penguins, dolphins
and many others have a darker coloration on the top portions of their
bodies and lighter portions on the bottom portion. It turns out that
this form of coloration can be very helpful to marine animals, both
living and extinct.
Penguins and many other animals have black or dark-colored tops and paler undersides. |
Modern leatherbacks' backs can become quite hot when exposed to the
sun. This is helpful since the turtle is a cold-blooded reptile that
needs to stay warm in order to move its body around, and that's not
easy for the leatherback because these widespread reptiles often can
be found living within the chilly waters of the arctic circle! Darker
colors – black in this case – attract more heat than lighter
colors, so therefore black coloration warms up the turtle more than a
lighter color would. While the extinct species of leatherback was
coldblooded, we have no idea whether mosasaurs and ichthyosaurs were
or not. However, even a warmblooded animal can find black
pigmentation on the top useful.
The leatherback sea turtle of today has the same coloration as its extinct relative. |
While mosasaurs use could swim at high speeds (probably as fast as
30mph) using their powerful tail flukes, they couldn't keep up the
high speed for long. So instead of chasing prey over long distances,
when mosasaurs found prey nearby, they probably stalked them like
great white sharks do today, far below their prey (mosasaurs ate
pretty much anything they could catch – fish, sharks, plesiosaurs,
sea birds, turtles and even other mosasaurs). Then when the moment
was right, the mosasaur would probably undulate its tail fluke to
launch itself upward and catch the prey in its five-foot, toothy
jaws. The black coloration of mosasaurs was probably used a lot like
modern predators: while stalking their prey, the black coloration
would help them blend in with the depths so that prey won't notice
them above. And from above, the lighter colored underbelly would make
a mosasaur or sea turtle hard to see because the lighter color breaks
up its outline. Cool, huh? While the turtle wouldn't be stalking
fast-moving prey, its coloration would probably be helpful in staying
out of sight from hungry predators. This is important because unlike
most sea turtles, the shells of leatherbacks aren't made of hard
shell, but rather are constructed of bony struts under the skin,
making the shell much easier to bite into.
Mosasaurs, such as the 50-foot Tylosaurus, could have used their coloration to remain concealed from prey until the attack! |
What about ichthyosaurs? Why was the one involved in the study
completely black? Well, long before the coloration of the creature
was discovered, scientists suspected that ichthyosaurs would often
hunt deep underwater because of their large eyes. One species of
ichthyosaur, Opthalmosaurus, has some of the largest eyeballs of any
animal in proportion to body size at four inches across! Their large
eyes would help them see both prey and predators in the darkness of
the water. If the species of ichthyosaur involved in this study was a
deep-diving creature, a lighter colored underbelly like the mosasaur
had would possibly give its presence away. But with an all-dark body,
an ichthyosaur has a lesser chance of getting detected. The modern
sperm whale bears similar coloration to this ichthyosaur – dark
colors all over the body – for this exact reason.
Opthalmosaurus had some of the largest eyes in proportion to its body size of any creature. |
All three of these amazing reptiles we looked at seem to be
beautifully designed for marine life, even down to the color of their
skin. Evolutionists are often puzzled why some animals bear
similarities to other animals if they just evolved. In fact, some
evolutionists have questioned whether or not the fact that the
animals involved in the study mentioned above had black coloration
because of mere coincidence. But how likely is that? I mean, this
isn't the only “coincidence” in nature; there are many animals
with features similar to other unrelated animals. For instance, four
kinds of animals are capable of powered flight: birds, bats,
pterosaurs and insects, and evolutionary scientists believe that the
power of flight evolved four different times! And it's the
same thing with the three marine reptiles mentioned earlier. How
likely would it be that creatures would be similar to other creatures
in this way?
The fact that many animals are often designed with features similar
to other unrelated animals should actually point us to the One who
created these amazing animals. Its way more believable that
these animals have similarities with other animals because they have
the same Designer. By looking in the first chapter of the book of
Genesis, we learn that God created mosasaurs, sea turtles and
ichthyosaurs on the Fifth Day of the creation week, no more than
6,000 years ago. Isn't it wonderful that God designed these creatures
to thrive in the environments He placed them in? So the next time you
see an animal that has similarities with another unrelated animal,
sit back and think about all the thought God placed into making both
of them and praise Him for that.
God provided many ways for the creatures He made to thrive in the environments they lived in. |
