Original Theory of Dino Fusion

Theory of Dino Fusion Biome Genetics
This new Dino Fusion theory comes from two of Professor OneStone's most humble assistants, Eppidiah and RobinCarr. We apologize for any errors in advance.

Introduction
This theory helps predict what dino you will get when you fuse two dinos. In the Dino Fusion process, each dino in the two fusion slots passes on its unique genetic marker, which is simply the Biome. The Biome marker or gene is summarized in the tables below for every dino and is the most important factor to consider when trying to figure out which dinos to fuse.

Dino Fusion is governed by the following two Laws of Dino Fusion, plus a small selection of general principles.

The First Law of Dino Fusion
Whenever two dinos of the same Biome are fused, the resulting dinos must come from only one Biome.

This new Biome is specified by the four equations below and completely determines the diagonal blocks in each fusion table.

These 4 equations are not considered laws, but may change at any time in the future at the whim of the Fusion Gods. However, we believe they are presently obeyed by all fusions in all other fusion tables. Of the hundreds of reported fusion recipes, only a very small number of reports appear exceptional. We believe they are all the result of entry errors such as putting the dino in an adjacent cell by mistake. It is remarkable that these 4 equations so clearly seen in the Tier 0 tables, in fact hold for all 3 fusable tiers.

The Second Law of Dino Fusion
Whenever two dinos from different Biomes, say Biome1 and Biome2 are fused, all the resulting dino(s) must, come from either Biome1 or Biome2.

The Universal Fusion Table From the above two laws, when combined will produce the Universal Fusion Table which applies to all tiers and both governs and constrains every fusion you do.

Warning Note : The Universal Fusion Table is entirely symmetric and does not depend on the level of the dinos you are fusing. The first two fusion laws do not depend on which dino goes in which slot.

Fusion Cycles and Dino Activation
In contrast to these fixed laws there is the magical and mysterious process known as Dino Activation. The Dino Fusion process comes in cycles or intervals. At the beginning of each new cycle, each dino is marked as Active or Inactive. We will also use the terms In-play or Not in Play. During this cycle you can only obtain Active dinos. You cannot obtain an Inactive dino. New Fusion cycles are often, but not always, started when a new dino is introduced. Which dinos are Active and which are Inactive can only be found emperically, say by constantly updating the Fusion Tables. At the beginning of each new cycle, the Fusion Gods must reset or reinitialize the variable which determines the "Active duty status" of each dino. Thus, a primary task for Fusion Table Guardians in the near future will be to determine empirically, then publish, a list maintaining the Active or Inactive status of each dino.

The following dinos are know to be presently Inactive, and so cannot be obtained from Fusion at least until the next cycle.

Inactive Dinos during this Fusion Cycle
In the current Fusion Cycle the following Dinos are inactive:
 * Spinosaurus
 * Protoceratops
 * Love Stegosaurus
 * Mesohippus and possibly also
 * Sabretooth Tiger

It is this mysterious resetting feature of Dino Activation that leads to the constant barrage of postings all asking essentially the same question, "Does anyone know how to get a Proto?" or "Does anyone know how to get a Spino?"

Although each new Dino Activation reset may appear to be at the whim of the Fusion Gods, it must still follow a few rules. For example, there must always be at least one Active dino for all Biomes except possibly one biome. And there must always be at least one Active dino from the critical Air and Tundra biomes which must appear on the diagonal blocks. Otherwise, some fusion combinations could never work!

Possible At Most One Dino per Biome Postulate during any One DInoFusion Cycle
We have in mind an additional Postulate but it must be more closely examined before publishing. This postulate would place a limit on how many dinos per biome can be acive at any time. In its stongest form, that limit is one.

Applications: Predictions and Filtering of Misreported Fusions
Although these laws seem innocuous, they actually have enormous predictive power. Here are some examples of their application.

Example 1: Predicting a Recipe for the Pony once that Dino becomes Active
Since the only Tier 0 Forest dino is the Stego, we can predict that the only recipes that could lead to the fusion of the new MesoHippus dino must have the form:

Stego + Non-Stego - - > Forest Dino or Dino from Biome of Non-Stego When the MesoHippus becomes Active in a future cycle, this is the only recipe that could give the coveted pony! The pony of course being found amongst the Forest Dino Outcome.

Example 2: Eliminating Erroneous or Naughty Fusion Reports
It was recently reported by a mischievious and anonymous wikiacon that the Pony could be obtained from the combination:

Mammoth(Toddler) + Mammoth(Toddler) - - > Pony (MesoHippus)

This erroneous report lead to the untimely and unfortunate demise of countless mammoths. However, it can quickly be dismissed using only the First Law, since each Mammoth comes form the same Tundra Biome. The only possible double mammoth recipes are:

Mammoth + Mammoth - - > Air Dino - - > [Pterodactyl or Brontornis]

Tip: Check the Tier 1 table below so you can see how we did that last step!

And since the Brontornis is Inactive in the current Dino Fusion cycle, in fact all such fusions gave Pterodactyls.

This explains this Friday's unexpected "Pteroodactyl Population Explosion" and "Massive Mammoth Extinction Event".

Example 3: Why so many Bambiraptors from Tier 2 Fusions?
This too, is completely explained by the First Law. Three of the Tier 3 Biomes are populated by only one dino!

Air - - > Bambi, Forest - - > Pachy, Desert - - > Minmi

while there are two choices for Tundra - - > Sabretooth or Giant Sloth

That means we can fill in the Tier 2 table with great specificity, as shown below.

The Tier 2 Fusion Table

Note inside the table Tundra - - > [Sabretooth or Giant Sloth]

DinoActivation: In the present cycle, the Sabretooth may be Inactive. If it is, it can be removed from inside the above table. Remember, the Dino Fusion laws do not say that all these dinos will appear. They simply say that these are the only possibilities! Which one actually do appear will depend on the DinoActivation process.

Example 4: The Tier 0 Fusion Table in the Current Cycle of Dino Fusion
In the present Dino Fusion cycle, at least 5 and possibly 6 of the 10 tier 1 dinos are inactive, including the proto, spino, love stego, brontornis and Pony. It is possible the andrews is now Inactive and most of the recent Andrews reports are actually old results. This means we can fill in the universal fusion table quite simple using:

Air - - > Ptero, Forest - - > Brontosaurus, Desert - - > Dime while Tundra - - > Lucky or Andrews?

a. First start with the universal fusion table. Along the borders, identify the tier 0 dinos being fused.

Tier 0 Fusion Table before DinoActivation is Specified
b. Now inside the table, fill in using only ACTIVE Tier 1 dinos. This gives:

Air - - > Ptero, Forest - - > Brontosaurus, Desert - - > Dime while Tundra - - > Lucky or Andrews?

Tier 0 Fusion Table after inputting the current DinoActivation values ( Active Dinos)

I left some of the Tundra icons so you can see the process. All Tundra results must be Lucky, with perhaps some old Andrew results in the mix. If you visit the Fusions Reported page, you can see out of the hundreds of entrees, only a very small number do not follow this pattern.

Exceptions: Wrong Theory or Wrong Data, You Decide
Let's look at a few of the exceptions, because if they cannot be explained away, the above theory has errors. We are counting on our team of wikiacons to give this page a thorough testing! We might be wrong and you will decide!

a. The brontornis results in the Mammoth + Mammoth blocks can be interpreted as an old Air dino that is now Inactive.

b. Any spino such as the one in the Mammoth/Anky block can be interpreted as an old Desert dino that is now Inactive.

c. The next exception is for you to decide. There are two brontos in the Stego + stego block. We believe they are errors, that belong in an adjacent block in the stego row or stego column. The first law predicts ONLY air dinos here. Similarly, the single lucky and the single bronto in the anky+para block may be data entry errors.

d. All the other exceptions appear minor and may be adjacency errors with the exception of the anky +anky block. That should be all Air dinos. We HOPE the two brontos and the single dime there are errors. If not, we need a modification that allows for rare exceptions like this. They are rare compared to the 13 pteros in this cell. One possibility is a rare exception for Adult + Adult combos, but more data and analysis is needed.

Example 5: The Tier 1 Fusion Table in the Current Cycle of Dino Fusion
In the present Dino Fusion cycle, it is harder to make conclusions about which dinos are inactive, because there are far fewer data points here. But the tier 1 table can be generally laid out as follows. a. First start with the universal fusion table. Along the borders, identify the tier 1 dinos being fused.

Now inside the table, fill in using only ACTIVE Tier 2 dinos. We are NOT certain which ones are active. However, the only Tundra Tier 2 is the Woolly Rhino so, Tundra - - > Woolly

Tier 3
Each biome table shows only the most basic form for the biome marker, which is all that is relavent in Dino Fusion.

History
1. The first law has grown out of the following observation by Eppidiah: If both dinos are the same, you sometimes have a "surefire" recipe. The first law generalizes the (same dino) part to same Biome. And a same-dino recipe will be surefire whenever, the resulting biome (Air or Tundra) has only one Active dino! For example, Woolly +Wooly is a surefire Bambi recipe according to the Two Laws of Dino Fusion.

2. The second law has grown out of the following observation, also by Eppidiah: If both dinos are different, you often get more than one result.
