We can infer, based upon their anatomy, that there were at most 24 or 16 total gangs of Tyrannosaurs at any given time, because it's only possible to throw that many different gang signs when you only have 4 fingers total.

The proof, for those who aren't binary literate:

`#  L  R`
`01 00 0002 00 0103 00 1004 00 1105 01 0006 01 0107 01 1008 01 1109 10 0010 10 0111 10 1012 10 1113 11 0014 11 0115 11 1016 11 11`

In this table, a "0" means a folded finger, and a "1" means an extended one.  The L and R columns represent the left and right hands respectively, and within those columns, the position of the number represents the position of the digit in question, so in the digraph "01", the "0" represents the left finger, and the "1" represents the right finger.

Computer nerds will note that the base ten number on the left is off by one from it's binary representation on the right.  That's because we are interested in the total number of possible Tyrannosaurid gang signs, not their counting system, which would start at zero (position 1) and end at 15 (position 16), whence we can infer that it would cycle over again.  If they had the concept of zero, of course, which would be difficult to figure out based upon the fossil record.

We all know the earth is only around 4000 years old.

Ate in packs, liked to bite each other.

Is this any different from [some] sharks?  I don't see any indication of wolf-like teamwork.

I could see if Mama Rex raised her babies and formed a terror (a terror is a group of T-Rexs) of T-Rexs; with the male Rexs doing the solitary thing.

Straight outa Chompton
Crazy coelurosaurian theropod
from an island continent named Laramidia
I got a clawed arm, and my blood's warm
and when I'm hungry I like to much on a sauropod.

Sup!

I don't see how they can assume that the Tyrannosaurs' bite marks came from their pack mates. It's more likely that, if they did hunt in packs, the bite marks came from rival pack members in conflicts over killed prey.

FTFA: ...the dinosaurs liked to head-bite each other.

Just like my ferrets, life uh- finds a way : )

Thanks for the LOLz too subby

yet_another_wumpus: Is this any different from [some] sharks?

Or komodo dragons

What gangs of dinosaurs might look like:

What if they aren't pack hunters and this is just a place where they swarmed to mate?

What if its a heavily used game trail so a bunch of individuals were on it?

What if one T-rex just kept going in a circle?

No wonder they seemed to have such bad attitudes. ;)

R-E-X spells'Rex' but I'm raw
See, coz I'm the motherfarkin villain
The definition is clear, you're the witness of a killin'
that's takin place without a clue
And once you're on the scope, your ass is through
Look, you might take it as a trip
but a dino like Rex is on a gangsta tip
Straight outta Chompton...

They were probably stuck trying to pass the mashed potatoes and eventually died of starvation.

The tracks weren't made by T. rex. though. Albertosaurus probably, with the outside chance of Daspletosaurus...

I worked on one Tyrannosaur out of Montana that was snacked on by several different scavengers. Gorgosaurus, even Daspletosaurus (its own kind, cannibalism). The raptor teeth at the site clearly belonged to the culprits that killed the beast though.

Barney with Attitude.

And then Raptor Jesus showed up.

Could've been a family too, just hanging out, or maybe getting together to mate... Not sure why it would be presumed that the entirety of their day is spent hunting and eating.

Hey Dinodork, can I get a professional opinion of my analysis?

I became a paleontologist because I was told there would be no math.

On a more serious note, many dinos used other parts of their anatomy for signalling, booth interspecies and perhaps intraspecies as well. We can't rule out these tyrannosaurs weren't using red dinofuzz to signal they are TyrannoCrips even without hand signals (and with their bird affinities, they may indeed have been seeing way into the UV end of the spectrum) . Plus Tyrannosaurs had extensive variability in lacrimal and jugal horns, unknown fuzz plumes, patches and tufts, striping, etc. You might have a hipster gang of tyrannos with coloration of spats and a monocle for all we know. The problem is that we don't have a clue how many variables there are.

Ancient refers to the time at the beginning of human history, no?

boy, this thread really deescalated quickly.

imtheonlylp: boy, this thread really deescalated quickly.

Dude, it's a dinosaur thread. You've just got to expect it to be full of nerds.

Sure, Easy-T, Ice Age, MC Rex, and Dr. Tre(ceratops) put together a nice package, but what about the influence of other raptors like (Arms) Too Short?

Everyone with a clue knows that the tracks were laid down by DJ Das, but it was still Ice T-Rex who mixed it in production.

What if one T-rex just kept going in a circle?

Then it would be a Heffalump?

I've just given up on worrying about what we don't know, and revel in the cool stuff we can. I dug up a bug sea turtle a few years back. One of the cool things we found while preparing it was that the critter had abrasions on the bottom of the plastron. We figured it was from dragging itself on the beach. Sea turtles only do that for one reason: laying eggs. So we could determine the specimen was most likely a sexually mature female (important when fossils are sparse for the taxon and the skeletal manifestations of sexual dimorphism may not be apparent). It's cool stuff to me.

Now that's cool.

gangstasaurus*

in case anyone was spell-checking that.

Mother Nature News? Legit source

So essentially, sea turtles egg laying behavior has outlasted Pangea. We can measure it literally in eons. Incredible. When nature gets something right... it stays right.
Thank you for sharing, that is the definitition of CSB without snark.

I feel ya, less binary mathematicals and more dinosaurs!

And just like that we're back on track, people! Boom!

On considering this, your story is a non-silly, real life example of the what I did with my, uh, first written thingy at the top of the thread.

Heh.

Think about it:  Given the evidence (Tyrannosaurs have two fingers on each hand, gangs use hand signals to identify membership), it's the only logical conclusion, though I must admit that I didn't account for arm position.

Bathia_Mapes:

Hey, dinodork, isn't that T. Rex head too big? Never noticed it until the gif made it repetitious enough to notice.

Oh Dittyboos! I go to sleep and come back and you killed the thread again. What are you doing?
