Need help for a project (silurian period)

Reply Tue 30 Jun, 2015 10:04 pm
Hello everyone ! Today, it's not going to be about dinosaurs.
I hope it's posted where it should.
Alright, thing is, I'm working on an independant video-game project about the Silurian period. It's supposed to be scientifically accurate, so I started documenting myself on the subject (that I knew well already).
I have all the infos I want about marine and aquatic life, but now I really need to know stuff like what "inland" grounds look like ? Was there dune deserts ? Rocky mountains ? What type of rocks ? Acid lakes ? Violent sandstorms ? What did and didn't exist back then ? To avoid anachronisms.
For the details, it is supposed to be located in actual Europe/North America during the Wenlock/Pridoli period (typical silurian).

And here are some early artworks that you might want to criticize : http://puu.sh/iEOKQ/143bfbb72d.jpg

Is there any reason youre avoiding the LLandovery?

Id include them all because what really defines the time pperiod are several good graptolite species that serve as index fossils.
As far as the stratigraphy, Id have to send you to individual source papaers on unique environments of deposition (desert deposits, aerial dunes, strewn fields, or even morainal deposits.)

Id start with a comprehensive search of the "Tretise of Invertebrate Paleontology", since, Im sure youve already used this resource.

There are Special Papers from the 1940's through 1960's in the US in which a state was producing stratigraphic series of Paleozoic through Cenozoic rocks (1940's terminology). Im not sure whether the GSA or some other organization has published a comprehensive review of stratigraphic environments nationwide.I use these old folios a lot. Most states have them on the web so you dont have to spend time getting silicosis in some dusty archive.

Theres a hell of a lot of stratigraphic and structural work being donefrom AFghanistan through the Horn of Africa right now, as well as in Australia. Australia can serve as a really good model of the planet since it has almost all the eras and epochs in its stratigraphy. Canada and US together serve well too. Trouble with Russia and China is that their work has been kept under wraps till recently.

CHina seems to be going in a paleo frenzy to "catch up" on documenting all these lagerstatte fossils that they seem to have.
Are you going to work in the colonization of the land by plant material?

I noticed a bunch of "age specific" games all of a sudden.
Your drawing (btw) is pretty good. Only comment Id have is that we see lots of the Silurian deposits of the Appalahians as the shallow sea deposits in which the early colonizers were living. You are showing the rocks after diagenesis , uplift, and erosion. Maybe youre showing the non marine into the Devonian?

Others have depicted Silurian land flora and fauna with these:
These are the Prototaxites: http://www-news.uchicago.edu/releases/07/070423.fungus.shtml
Don't forget them.
Here is some description from the link above:
Prototaxites lived worldwide from approximately 420 million to 350 million years ago. During this period, which spans part of the Silurian and Devonian periods of geologic time, terrestrial Earth looked quite alien in comparison to the modern world.

Simple vascular plants, the ancestors of the familiar conifers, ferns and flowering plants of today, began to diversify on land during the Devonian Period. “Initially, they’re just stems. They don’t have roots. They don’t have leaves. They don’t have anything like that,” Boyce said.

Millipedes, wingless insects and worms were among the other organisms making a living on land by then, but no backboned animals had yet evolved out of the oceans. “That world was a very strange place,” Boyce said.

Although vascular plants had established themselves on land 40 million years before the appearance of Prototaxites, the tallest among them stood no more than a couple feet high. By the end of the Devonian, approximately 345 million years ago, large trees, ferns, seeds, leaves and roots had all evolved. “They’re all there. They just exploded over this one time period,” Boyce said.

I would suggest contacting some of the researchers mentioned in the article and asking them to describe the environment at that time. They usually love to talk about their field of interest and I think (hope) we all would love to see a game or film with relatively accurate depictions of the environment back then.

Good luck.

Thanks for your answers Farmerman,
First, I don't exclude the Llandovery at all, I was just giving examples. I'm trying to hit a typical silurian world. I'll give a look at those stratigraphy folios if I find them.
I'm not trying to show the Devonian, so how should the rock be more looking like if there's anything wrong ? I'm pretty sure there are example of modern rock formations that existed back in the Silurian ?
Also, yeah, I will treat the colonization of plants, but I guess it's pretty easy to know somme of the species that existed back then and where, and I assume they were all growing close to the water. I heard about moss forests and such.

I didn't see your answer until now, rosborn !
Thanks for the images ! I saw those giant fungus formations on the web and I was hoping I could use them. This is very exciting to know such things existed, I'm sur it'll look very impressive ingame too.
The goal though is to represent all of this flora accurately, so thanks again !

Btw, here's an old artwork I did for it and I did something similar on the upper right corner : http://puu.sh/iEQlA/f8b1236671.jpg

Theres a few upper Silurian redbeds in the Us and Canada. (Im not certain about other areas without looking at the sheets(but thats your assignment eh?)

Glad I could help. I think you should definitely try to contact those researchers in the article. I'm sure they have a much better vision of what things were like during that time.
