It's 2015 [it was drawn and uploaded to FA and DA last year] and I keep seeing new terrible "reconstructions" of extinct animals. Especially archosaurs and early therapsids.
Here's a dog done with as many mistakes as I could think of.

-wrong skin covering, because every animal is scaly
-stripes stripes stripes
-every animal is at least partially green
-impossible colors - carotenoid and structural colors on a mammal in this case
-no/very little lips
-visible, displaced jaw muscle
-every crest is supporting a colorful covering
-shrink-wrapped skull, worse than on a sick, starved animal
-no cartilage
-glowing iris instead of reflective tapetum lucidum
-slit pupils because it's a carnivore
-perfectly white teeth
-males have to be colorful, even ambush predators and prey animals
-random foliage and location
