Mesozoic Biology

Mesozoic Biology is one of many other dino addons, but, this one is special, because Mesozoic Biology aims for Scientific accuracy! Many effort has been putted into it to make the most accurate models ever, with assesory by experts on the field, we hope you like it!

Mesozoic Biology as said before, is an addon that aims for Scientific accuracy, and, archieves it, so, if you want to see how dinosaurs really were, this is your addon! So, let’s get into it!

In this beta, we have 7 dinosaurs, Tyrannosaurus rex, Triceratops horridus, Spinosaurus aegyptiacus, Edmontosaurus annectens, Diplodocus hallorum, Ornithomimus velox, Concavenator corcovatus and a prehistoric fish, Mawsonia gigas, all of them are tameable, sittable, rideable, and saddleable (saddle is optional)

First of all, we have the fossils, they are the remains of the colossal creatures that lived on the past, they spawn in every biome and there’s one for each dino

Then we have the cloning machine, to craft it you need the items shown in the image, it will give you a building set block that you have to break in order to get the cloning machine, after that, the machine gives you a dino egg depending on the fossil you give to it

Then, we have the eggs, for now all of them are the same, but in the future they will have special models and textures for each of them!

Now let’s go to the real focus of this addon, the dinosaurs!

Tyrannosaurus rex

Tyrannosaurus roamed north america in the late cretaceous, this guy has a big change during pubertry, tame one and watch him grow!

    Can you add pteranodon and dimorphodon?

  2. Cobra48 says:

    This mod is amazing!
    I wanted to play Fossils and Archeology, but its such a hassle just to change the version.
    I Just have a few suggestions in order to change my rating to 5 star:
    -Make the cloning machine a block instead of an entity (just like in Fossils and Archeology)
    -Add new inventory sprites for the new feature, not just spawn eggs
    -Make fossil skeletons work a little differently (they are too common, try to make the skeletons rarer)
    -Add Fossil Blocks that can be found in caves, mountains, and cliffs.

    Other that that, this mod is surely amazing!

    • Welp, thanks for the feedback! And about your suggestions, due to limitations of MC we can’t make custom blocks have custom models or trading options, that’s why the machine is an entity, and for the fossil blocks, I don’t figure out how to make blocks naturally spawn yet, but we will add custom sprites for the functions and we’ll also make fossils rarer

  3. Anime Child says:

    Love the addon! Just one question though… Can you add fossil statues?
    If you can that would be great!
    I want the fossil statues to be craftable please.

  4. Inverted waffles says:

    Love this update and i cant wait to see what is coming for the next update.


    Pls add a pterodactyl if you can Great mod thx for making it

  6. Cat_trooper says:

    Very good Addon but I would like some things: conc’s foot steps are far from matching with the speed and it looks like it’s just sliding , I would like that ostrich Dino would run away at the same distant as at least 10-20 away , and finally I would like it if you can find a way to and a custom fossil block so we actually need to mine fossils (if you can it want to) but so far every else is really good

  7. J_dhen0030 says:

    Bro remember me I hope you put some sounds in it

  8. i like jwfk says:

    next update a mosasaurus!!!!!!!!!!!!!!

  9. Davianortis says:

    Am I the only one who cant craft or spawn the cloning machine?

  10. The great Q says:

    “Unlike other addons, mesozoic biology aims for scientific accuracy” talk about false advertising all the dinos have insane stats and even the diplodocus is super fast.

    • Welp, first, the stats, we did some serious studies to the stats of the creatures of minecraft that exist irl to make them, minecraft is an unconsistent game, lava should instakill everything, TNT should kill everything on the range of it, and more, and then, diplo’s speed, the speed of diplodocus is estimated on 25kmph, and steve’s speed is 12kmph aprox, so, diplodocus has an accurate speed, maybe it should even be faster, I’m surprised no one has criticized the fact that Spinosaurus isn’t quadruped tho

  11. M.M.16 player says:

    Can you add therizinosaurus next update?

  21. Irish Jevil says:

    Very good mod, but could you make the eyes on some of the dinosaurs more realistic and less cute?

  22. Metal sulvio says:

  23. Kain no kyoukai says:

  24. akbarIndo47 says:

  25. Flame X says:

    Hey creator!!! I loved your mod… Can you make a mod having Cenozoic animals…. If u can plz make a mod on it….😊😊😊

  26. GhettoSaurus says:

    Okay I like the idea with this addon but I have some problems with this.

    1. T. rex most likely didn’t have feather covering as an Adult, also for a predatory animal if you still want to use the yellow I suggest darken the tone.

    2. The textures in general feel out of place for a Minecraft addon in my humble opinion, maybe you should get someone else’s to retexture the models so they could come off a little natural.

    3. This one is a question but are you guys working on growth stages for the animals?

    4. Another one is will there be sexual dimorphism?

    • 1-Tyrannosaurus was probably feathered, as you can see in this video, it’s a bit outdated, but the info related to the topic (feathers) is mostly correct
      Also, the coloration of dinosaurs is totally unknown, and a yellowish tone would combine with the semi swampy habitat Tyrannosaurus lived in

      2-If you are talking about colors, welp, all of them have justifications and, Spino will come with a new and more natural coloration in next updates, while with Trike, his blue coloration means extreme danger, due to it being stronger than a T. rex, so if a T. rex sees it, it will know is dangerous and go away



  27. SuperMetaKnight2020 says:

    There are a few non scienfcally accurate parts of this addon.

    1. The Dinosaurs Colour palettes are wrong, The Trex should be Brown or Dark Coloured so those the other 2 dinos.

    2. Nerf The HP and Damage, make them have up such as 80hp because these things are stronger then the Ender Dragon

  28. The loop says:

    Hey xenomorph_and_Dinosaurs, please make the the saddle alittle bit bigger on the triceratops because it’s big head blocks the view in first person view, That’s all I have to say or then the rest of your add-on like the textures and behaviors is Amazing!

  29. Nexha says:

    i cant tame any of them i offer spinos and rexes bones but nothing pops up same with tricertrops can you fix it pls?

  30. Indoraptor145 says:


  31. Nobody knows what dinosaurs sounded like, but can you add sounds?

  32. Why do every modded creatures in literally every single bedrock addon deal so much damage? The mods in Java balanced this by adding weapons capable of killing them and giving them actual lores, but bedrock addons constantly add basically armies of Saitama for no reason. What kind of trend is this?

  33. Arachnology_Bruh says:

    You cannot begin to imagine how grateful i am for a good quality realistic Mesozoic addon.

  34. XxDracoAzul_GamerxX says:

    You can make a more big Spinosaur and Brown Rex and more designs to all dinos?

  35. XxDracoAzul_GamerxX says:

    You can make a more big Spinosaur and Brown Rex?

  36. I_Will_Judge_You says:


    • Why is it inaccurate? All the models were carefully assesored to be accurate, and all the precautions were taken to do it right

      • I_Will_Judge_You says:

        Alright, let me tell you why, let’s start of with the blur triceratops. The pigment of blue is very rare in creatures, even today, it is so rare that there are very few animals that are in this color, and also, how would the triceratops hide from its predators, it can’t camouflage! Because it is blue! You might make the excuse that it is brightly coloured so it can pretend to be toxic, well, do you know how a predator finds out wether a prey is toxic? They eat it. If nothing happens, they eat the whole species, and guess what? The triceratops is blue! So it would be easy to spot in the wild!

      • I_Will_Judge_You says:

        Now let’s do the tyrannosaurus, same reason as the triceratops, it is a bright colour. The spinosaurus model is realistic, but the color is not. Alright, now the final problem: the sitting. The way they sit is so scientifically unnaccurate that if dinosaurs sat like that they would break their legs. If they even could sit like that, they would have to have a ball and socket joint on their thigh bone joint, which is impossible, and it’s not there, and even if it was ther, how would they get back up?! Those are the problems I see.

      • I_Will_Judge_You says:

        Awesome addon, btw. Just these problems.

        • First of all, Triceratops coloration is blue not because of being toxic, is because of being extremely dangerous, and the predators wouldn’t attack it, but I need to admit that it’s too bright, maybe it’s because all of our skins are based on prehistoric park dinos, next thing is the Tyrannosaurus, the colors of it aren’t that bright, they fit with the place they lived in, and, the sitting, yes, it’s antinatural, it’s going to be fixed in next updates, and the spinosaurus coloration has the same justification as tyrannosaurus, and, another thing I need to mention, they are all that bright because we are also adding females, and we want to make a relatively big constrast between genders, basing this off on modern birds, thanks for the feedback!

          • I_Will_Judge_You says:

            Oh ok! Those where just little problems I had with the color and sitting, the models are fine and I understand what you are aiming to do now. But as far as studies go and every prehistoric expert I’ve met, they’ve never showed the coloration of the triceratops to be blue, same with the T. rex. Other than that, great addon! Thank you for your time!

  37. Good job! The models and behavior is pretty good but the textures are too colourfull please make them less colourful and more combinations

  38. I_Will_Judge_You says:

    The spinosaurus is the most accurate out of all of them, except for the colour!

  39. alessandre says:

    you can make a prehistoric crocodile like sarcosuchus purussaurus

  40. π play says:

    How are the generation rules?

  41. Avian Crux says:

    It’s amazing honestly

  42. Also, I forgot to say that Capitan Concavenator also worked on the addon! And I also forgot the link to our discord:

    • Nexha says:

      i cant express how grateful i am this mod looks and is amazing but can you pls make the dinos a bit more balanced they seem too op and so easy to tame can u make them like 250 health and 50 attack and rideable i wanna use it with other addons that add diffrent bosses with like 500 health so it would be nice to have my rex with me they just seem too op and too easy amazing job thank you so much

    • alessandre says:

      friend I am not convinced the spinosaurus is very colorful

  43. garrette says:

    What are the types of dinosaurs you plan on adding?

  44. M.M.16 player says:

    Good addon can you add more dinosaurs next update please!
