In general, the difference between ammonite and nautilus in terms of shell is that the shell of ammonite is slightly thinner, the body tube is relatively simple, and the next wall extends toward the shell mouth.

In addition, the most important thing is that the ammonite has complex sutures, while the nautilus has no sutures. It is the line between the ammonite next door and the inner surface of the shell wall.

The sutures of other cephalopods are simple arcs or straight lines.

But the sutures of ammonites are quite complicated, so any description and classification of ammonites must be based on the discussion of sutures.

The part of the suture that bends in the direction of the shell becomes the saddle, and the part in the opposite direction becomes the leaf.

Then, according to the different positions in the shell, they are named as the ventral saddle, ventral lobe, dorsal saddle and dorsal lobe. According to this, there are several types of sutures.

One, consisting of a few simple saddles and leaves, called ammonite sutures, possessed by most Paleozoic ammonites.

Two, consisting of serrated or frilly leaves and rounded uninterrupted saddles, are called dentate sutures.

Todonites are typical examples with this type of suture, which dominated the Triassic of the Mesozoic.

Third, the sutures that are bordered by leaves and saddles and differentiate into many leaflets, called ammonite sutures, mostly appeared in the Jurassic and Cretaceous.

There are several different schemes for the systematic classification of ammonites, one commonly used is to divide the subclass of ammonites into 9 orders:

Similar to ancient ammonites, ventral and posterior neck body tube, with full lateral leaves or lateral leaves moved laterally during ontogeny to form more umbilical leaves, Devonian.

It is further divided into 4 sub-orders.

Stemlithiasis, the shell is straight or arcuate, spherical carcass, with ventral lobes, sometimes with full lateral lobes.

The suborder of ammonites without ridges, annular or convoluted shell, early umbilical, with full lateral leaves, early-middle Devonian.

In the suborder of ancient ammonoids, the umbilical lobe remained at the umbilical line or shifted laterally during the ontogeny, late Early Devonian-Late Devonian.

In the suborder Pyridophytes, during ontogeny, lateral and ventral lobes split to produce a series of rib and episodic leaves, early Late Devonian.

Prismatic ammonites, ventral cuboid tube, oval carapace, in the process of ontogeny, 1 to several lateral leaves in the suture are formed by the lateral saddle cleft, Middle Devonian-Permian.

It is further divided into 2 sub-orders.

The universal laws of energy transformation and conservation are the concrete manifestations of all macroscopic processes involving thermal phenomena.

It is one of the fundamental laws of thermodynamics.

The first law of thermodynamics is a way of expressing the laws of conservation and conversion of energy.

"But the fastest one is now ready to open the missile silo and will launch in 1 minute! The missile is expected to be in the stratosphere, intercepting 3 unknown objects!"

"The stratosphere? Can it really be intercepted?"

Hearing this, Zhou Wenwen couldn't help frowning, called up the information, and thought about it carefully.

The stratosphere is from the troposphere up to about 55 kilometers high.

This layer is where ozone is concentrated in the earth's atmosphere, especially in its lower part, that is, at a height of 15 to 25 kilometers, the ozone concentration is the largest, so this layer is also called the ozone layer.

Since the ozone layer can absorb a large amount of solar radiation heat, the air temperature is greatly increased, so the biggest feature of this layer is that the temperature increases with the height, and the temperature increases to the maximum value at the top.

Although there is very little water vapor in the stratosphere and weather phenomena are relatively rare, with the launch of meteorological rockets and satellites, it is found that the changes in air flow in this layer are closely related to the weather changes in the troposphere and affect each other.

Now Zhou Wenwen is most concerned about Tony's side, he asked.

"Does Tony already know? How is he now?"

Hearing this, the hunter quickly called up the satellite and tracked Tony's signal, according to the data.

"Jarvis connected to the military networks of various countries, and notified Tony after the first discovery. Now the satellite has detected that he is flying to the Johnson Space Center in Houston."

"Johnson Space Center? Where is this?"

Hearing the unfamiliar geographical term, Zhou Wenwen couldn't help showing a stunned expression, and the hunter had to call up the data and replied.

"Johnson Space Center is also Lyndon B. Johnson Space Center, JSC. It is located on the west bank of Clear Lake in Texas, about 40 kilometers away from downtown Houston, covering an area of ​​4.38 × 107 square meters."

"There are more than 140 buildings of various sizes in the center, which house various equipment and facilities for space activities and applied research."

"An agency of the Johnson Space Center NASA that has been coordinating and managing human spaceflight missions since 1961. Its mission control headquarters are located at Johnson Space Center."

(But none of NASA's manned aviation missions since Gemini 4 in 1965 have been commanded from here. Previous Mercury missions have been commanded from the Langley Research Center in Virginia.)

Hunter: "Currently the Johnson Space Center controls the flight of the Space Shuttle and the status of the International Space Station."

"In addition, the Johnson Space Center has an astronaut training center. The entire facility covers an area of ​​​​655 hectares and has more than 14,000 employees."

"The center leads various research projects related to human exploration and development of space and space civilian programs, mainly serving NASA and some commercial institutions..."

"...Master, don't read it for too long. Help me connect Tony's phone."

Seeing that the hunter wanted to continue talking, Zhou Wenwen quickly interrupted the hunter and issued a new order. The hunter naturally accepted the new order.

"Yes, master, connecting the satellite line, the connection is complete."

As soon as the hunter connected the satellite line, Zhou Wenwen, who couldn't wait, asked, but after a while, Tony replied, and the noise was loud.

"Tony, where are you?"

Tony replied, "I'm off...//--/--Johnsonxdryfrxrf Center~www.readwn.com~Where are you?"

"I'm in the sky over Qatar now, and I'm going to use a laser weapon (space-based weapon) to intercept it. What about you, what are you going to do?"

Because space-based weapons need concealment, Zhou Wenwen did not directly mention space-based weapons, but replaced them with laser weapons, which would understand that Tony, who was interfering with the call at the space center, started the Mark 2 armored flight without hesitation. In the air, I decided to continue the call first.

"You're going to use a laser weapon, I'm afraid it's not enough to fight three at a time, and is your weapon powerful enough?"

The clever Tony heard the concealment in Zhou Wenwen's words, and directly asked the crux of the matter. After hearing Tony's words, Zhou Wenwen, who lacked knowledge in this area, couldn't help but get stuck for a while, and quickly changed the subject and said: " What are you doing at Hughes?"

"I'm afraid my armor Mark 2 won't be able to fly into the troposphere, or even break through the tropopause, I learned from Jarvis..."
