InterestHigh interest
Posts demonstrate a high level of curiosity, especially regarding the new imaging techniques and evolutionary insights.
EngagementModerate engagement
Several posts delve into technical details and give their analysis, indicating moderate engagement.
ImpactModerate impact
The discussions suggest the research could influence our understanding of ancient marine life, though some posts focus on descriptive summaries rather than broader implications.
Abstract in brief
New CT scans of the fossil Helicoprion reveal that its spiral tooth whorl filled the entire lower jaw and was supported along the midline, clarifying its skull structure.
The study shows that Helicoprion's upper jaw connected with the skull in two places and that its hyomandibula was not involved in jaw support, identifying it as part of the stem holocephalan group.
The findings highlight unique features like lateral cartilage to support the tooth whorl, illustrating an advanced adaptation for continuous tooth addition and retention, representing the peak of its group’s diversity in Late Palaeozoic seas.]

Which suggests they mostly ate soft-bodied animals that may have had outer shells, like modern squid or nautiloids.
The buzzsaw arrangement *may* have been ideal for biting and pulling the squishy bits out of the crunchy bits with less effort than a horizontal array of teeth.

سمكة Helicoprion تحتوي على فك دائري مع مجموعة لولبية من الأسنان الحادة..وهو نوع من أسماك القرش القاتلة التي يصل طولها إلى 7 أمتار..وقد عاشت في المحيطات قبل ما يقرب 270 مليون سنة ..وتعد أكبر وأخطر مفترس عاش في المحيط.

HELICOPRION UN PEZ EXTINTO CON UNA SIERRA CIRCULAR EN LA BOCA
-Peces cartilaginosos similar a tiburones
-Extinto hace 225 m.a.
-7,5 m
-Posiblemente comían animales blandos como calamares
-Muchas teorías ubicación de dientes pero ya está resuelto (Foto 1)
