Development of early tetrapods like embolomeres may not have involved metamorphosis

1 bit pixel art of a lagoon-like environment with plant life, rocky areas and light dancing on the water's surface. There is an adult embolomere watching a young embolomeres swimming around, looking like a smaller version of the adult, with four limbs, a crocodile-like face and a paddle tail. In the background are lots of bubbles in the water and the silhouette of another adult embolomere in the distance.

For something completely different

~ 300 mya fossils reveal first vertebrate land dwellers not what we thought

Shift from water to land didn’t require amphibian-like metamorphosis

Direct development of stem tetrapods across the fin-to-limb transition🧪

Image of embolomere fossil Study suggests that embolomeres and other early four-legged land walkers were direct developers, growing from smaller to bigger versions of their adult selves.

Exceptionally preserved hatchling fossils demonstrate that early tetrapods didn't have an aquatic larval phase but instead developed directly into juveniles. Metamorphoses, like what you'd see in modern amphibians, likely evolved later! 🧪

New paper! Embolomeres are often portrayed as amniote forerunners. I describe a well-preserved braincase of the embolomere Archeria, with additional evidence that this is probably not the case:

Last Thursday, a publication I coauthored was published in The Zoological Journal of the Linnean Society. In the publication, we provided a revised diagnosis and description of the Pennsylvanian embolomere Calligenethlon watsoni. The data can be accessed @ MorphoSource.org via media # 0006677245

Is that supposed to be an embolomere?

I decided that I wanted to do a fully-traditional paleoart project to see how it would change my process. I created a series of tonal drawings to decide on the overall/ compostion, setting and pose, as well as giving me something to reference for the final painting stage. #SciArt #PaleoArt
A tonal pencil sketch of a Rhizodus hibberti lunging towards the shore to snap up an unfortunate embolomere that had been sent flying through the air from the force of the impact from the huge predator. A tonal pencil sketch of a Rhizodus (with slightly less elongate body proportions) swimming along the riverbed alongside other Carboniferous scarcopterygians (1-2 meter long Megalichthys) which are dwarfed by comparison. This tonal pencil sketch was the prototype/ block-out for the final acrylic painting. A Rhizodus is seen breaching out of the water with a smaller sarcopterygian fish in its jaws. The edge of the Carboniferous swamp can be seen in the background. In the final version I decided to change the fish in its jaws to an Embolomere (a stem-tetrapod or possibly reptiliomorph) as I thought it was important to show that animals we characterise as being less-advanced or more basal (e.g. fish often mistakenly being considered 'less evolved' than land animals) can still completely dominate in their ecosystem and being 'more derived' doesn't mean that an animal is guaranteed to succeed in its environment. The final tonal pencil composition sketch for this Rhizodus project. This one shows the huge Rhizodus swimming alongside a Megalichtys, a fairly-closely related sarcopterygian as well as several smaller Rhadinichthys (3 can be seen swimming in the background) which is a bony fish and common in the Wardie shale where Rhizodus remains have been discovered. This scene is set in the dark so the animals are lit from beneath, which I think adds an interesting, eerie effect.
