Prehistoric Beasts

MOD ID 2003934830

I've always felt like there weren't enough unique dinosaurs in Ark. That's why I decided to create my own mod. Each dinosaur uses a custom model made by me! Featuring both obscure and more in the spotlight dinosaurs, Prehistoric Beasts is the mod for someone who loves dinosaurs.

I try my best to create interesting dinosaurs that fit where I think Ark is lacking. From adding more dinosaurs that allow rider mounted weaponry to more unique taming methods, each of my dinosaurs are special. So join along in my journey to add a few more beasts into this wild game!

Huge thanks to all that support the mod! I couldn't have done this without you =D

Totally agree. Thank you for letting us know that method resolved your issue. We have had others with the same issue, so its good to know this seems to be a reliable suggestion to fix it. Just after the update published on February 10th Steam was acting weird (for example, it told me this mod and ARK Additions were removed from the workshop) so I wonder if that wasn't part of the cause in all of this. Prior to that update, we had no reports of crashes.

I had Disconnects when near Dracovenators on Crystal Isles, fully reinstalling mod on Client and Server fixed it. I do wonder why the update system is so terrible, it shouldn't have corrupted downloads in current times.

Pioppo I have no plans on a TLC for Tsintao. That is one of my newer creatures, and I am happy with how it turned out.

would you do a tsintaosaurus TLC in the future?

Ornithocheirus do spawn at a similar rate as Pelagornis, but they do have a hard limit for how many are allowed to spawn. Are you in singleplayer or server? If singleplayer, do you play with hibernation on or off? For Neovenator spawning in base, it would depend on how large the base is and if there's a large enough gap for it to spawn. I'm not sure what the exact number is, but I do know depending on where you spawn creatures can spawn in bases. For Siamosaurus, I am unsure why you would be having an issue with them spawning. This is the first I am hearing of any issues with Siamosaurus spawns.

So, on further research and a 1.0 spawn rate, I found about half as many Ornithocheirus. maybe 1/20 pelagornis/pteranadon. Manageable but still seems excessive.

I'm on Ragnarok. I've boosted spawn rates for everything to 1.2 from stock, but they're still spawning at nearly the rate of Pelagornis or Pteranadons if i fly over a new area.
The neovenator issue may not be mod-related. I spoke to someone else that reported ARK will occasionally spawn something in the middle of the base. I expanded that particular base and stuck a high-level Rex right at that point to hopefully break that spawn.
I've also noticed a issue with the Siamosaurs, that they don't seem to be spawning properly or re-spawning. I've had to exit and log back in to get them to spawn. This may be another issue with ARK though as pre-mod I had to do a dino-wipe to get more of everything to spawn.

The gustave siamo code is not listed, as this is essentially a tamable alpha. for balancing reasons it wasn't provided

Spawn Code for Gustav Siamosaurus ? Cant find them in the Documents. Thanks

@DYLAN1 This latest update removed them from spawning around the Volcano.They spawn in the desert dunes on Ragnarok. I do not know how they would possibly still be around the volcano/wyvern scar after a wild dino wipe.
