ERBianism

Poul Anderson did not write any Edgar Rice Burroughs pastiches unless we count that single recently referenced passage. See:

Two Virtual Realities

- although it would have been well within his abilities to do so. 

The ingredients are present for all to see. The most basic is that another planet must harbour both a fully human race into which our hero can marry and also savage beast-men whom he must fight. A second ingredient is a gallimaufry of dangerous wild animals including, in the Land that Time Forgot and the Earth's Core and on SM Stirling's Venus, dinosaurs coexisting with human beings. Stirling has done what Anderson could have done, including a scientific rationalization for the retro-Solar System.

At the end of The Sky People, there is a two-tier transition to the alternative Mars which we will reread next.

Any ERBian cast of characters includes an obvious villain/traitor/saboteur etc. Stirling, like Anderson, is considerably subtler in his characterization. (Not difficult.) Marc dislikes the pompous British guy, Blair, so we expect a major conflict between them but that does not happen but something does happen about Blair...

Introducing the wheelbarrow works as well on this Venus as it does in ancient Rome.
