Did this art in February, however I never posted on sites like deviantart or here due to some issues I had, which have now been fixed.
A sort of world building artwork. In the Saedraverse, humanities Homeworld is Anewra, that at current has very much Earth historical elements that may change.
Unknown to humans, the planet Anewra is actually hollow. This world below is known as Tir Na Nog named by Santurihi, here they built part of Agartha & as life returned to the universe gathered an assortment of creatures doomed to be extinct on the surface. Both ancient, recent and unknown to humanities fossil record.

Image: Saedra Ewan took a ride on the Spinosaur Scathach (based on outdated depictions) found & chose to observe a trio of Anewrian Spino's (current accuracy) with surrounding animals, a herd of Edaphosaurs in the background, a recently extinct Amur Tiger and a couple Alpocs, a more herbivorous cousin of ambulocetus. Unknown to the fossil record but did appear in the myths of Celtainn
