Dawn at Las Hoyas

This scene takes place at Las Hoyas Wetland (Cuenca, Spain, Lower Cretaceous, Barremian stage, 129-125 m.y.) and depicts two specimens of the basal ornithomimosaur Pelecanimimus polyodon, focusing on a putative sexual dimorphism of this species. Sexually dimorphic features include not only the color and morphology of the cover of protofeathers, but mainly on the size and color of the gular pouch. This structure has been proposed for this species, based on the integumentary impressions found on the holotype fossil. In addition to Pelecanimimus, the scene shows some more plant and animal species: the tree fern Weichselia reticulata (background), the conifer Frenelopsis ugnaensis, the albanerpetontid amphibian Celtedens ibericus (captured by the female Pelecanimimus) and several enanthiornitid birds (Eoalulavis hoyasi and Concornis lacustris) The latter are taking flight apparently for the same reason that has startled the male Pelecanimimus in the foreground, perhaps a disturbing sound, or an approaching predator?

Very good, how have I not seen this before?!

Haha no idea ¯\_(ツ)_/¯
Anyways, thx for liking

A fantastic representation of this ecosystem. The two Pelecanimimus look convincing, although I don't see feathers in their arms. By the way, an excellent work friend.

Thank you (Gracias!)
But they do have (proto)feathers in their forelimbs. Do you mean by any chance pennaceous feathers, as in dromaeosaurs or in derived ornithomimosaurs? If so, I decided not to represent those, as Pelecanimimus was a basal Ornithomimosaur and evidence suggests that, if it had feathers, those would be protofeathers.
Anyways, thanks for liking, much appreciated :)

No, I'm refering pennaceous feathers. There isn't directly discovered on Pelecanimimus, but there is evidence on a relative, Ornithomimus. Check this link more info: phys.org/news/2015-10-ornithom…

Yeah, but Pelecanimimus was basal to ORnithomimus, so I kinda made the conservative call there and just depicted protofeathers.

hmm, I see your point. Of course you can depict them as you mostly prefer. There is no direct evidence of integumentation on Pelecanimimus, so any reconstruction is primarily speculative.
HSilustration's avatar
Yep, paleoartistical reconstructions are just hypotheses.

I don't think the trees in the background existed in Las Hoyas

Anyways, you did an amazing job on this piece, especially with the feather texture.

This blew me away when I saw it on TheSummonENGH fb page. Do you have any advice for someone who is terrible at scenes/landscapes? 
HSilustration's avatar
Thank you :)
Actually, I don't consider scenery and landscapes to be one of my strong points, what I'm doing myself to improve at it is to study, paint studies from real-life landscapes, so I guess I would encourage you to do the same.

Okay great advice, thank you!
