InterestHigh interest

Many posts show high curiosity about Dimetrodon, with references to videos, facts, and its evolutionary significance.

EngagementModerate engagement

Posts frequently reference specific videos, mention scientific concepts like synapsids, and share personal opinions, indicating moderate to deep engagement.

ImpactModerate impact

Discussions suggest that the topic influences viewers' understanding of evolution and extinct species, though primarily within educational or enthusiast communities.

Abstract in brief

  • The study investigates the bone structure and growth patterns of hyperelongate neural spines in the extinct synapsid species Sphenacodon and Dimetrodon to better understand their dorsal sail functions.
  • Histological analysis shows both species have similar bone tissues, with variations along the spine related to muscle attachment and growth, indicating differences in soft tissue and possibly in dorsal sail shape.
  • Findings suggest Sphenacodon likely had a short dorsal crest, with the bone features providing insight into the evolution and potential functions of these dorsal sails, though their exact role in thermoregulation remains unclear.

@dinocup2 I have to go with the Dimetrodon because while it's technically not a dinosaur, it's a stem mammal. It's pretty cool and I have a strong love for these guys. Also, here's a video by @EonsShow about the Dimetrodon: https://t.co/3vdipbBKRF https://t.co/C6AOsRnopV

@grossberg4ky It’s a bit complicated. As stem mammals, Dimetrodon and it’s relatives are related to the animals that would give rise to the therapsids(of which all modern mammals are members of), but are not directly responsible for them. Eons has a great video too... https://t.co/MLQzcH7kO1

@eggnogyummy @ZeekZag Nah, birds and reptiles evolved from different animals, synapsids went on to create mammals. And yeah, the earliest ones LOOKED a lot like dinos/reptiles, but had a lot of key differences that put them on our team. https://t.co/fLOOIYTV6z

@Yammedup @PulpLibrarian Yeah, it’s what’s called a synapsid, which is the branch of reptiles that mammals evolved from. It’s also long gone (~40 million yrs) by the time true dinosaurs show up https://t.co/PXyuYDqil8
