190-million-year-old “Sword Dragon” fossil rewrites ichthyosaur history

A newly identified ichthyosaur from the UK’s Jurassic Coast is rewriting part of the prehistoric playbook. Nicknamed the “Sword Dragon of Dorset,” the three-meter-long marine reptile lived during a poorly understood window of evolution when major ichthyosaur groups were disappearing and new ones emerging. Its beautifully preserved skeleton — complete with a blade-like snout and possible last meal — helps pinpoint when this dramatic transition occurred.

Torvosaurus: Beast of the Week

Today we are going to look at a huge Jurassic predatory dinosaur, Torvosaurus tanneri!  Torvosaurus lived about 150 million years ago during the Late Jurassic period. Its bones have been unearthed in Colorado, USA, Portugal, and possibly Germany (Europe and North America were not as vastly separated back then, remember, so a lot of the dinosaurs on each of them from that time shared recent ancestors).  From nose to tail it measured up to 36 feet (about 11m) and would have been among the largest,

Baby dinosaurs were the backbone of the Jurassic food chain

Despite growing into the largest animals ever to walk on land, sauropods began life small, exposed, and alone. Fossil evidence suggests their babies were frequently eaten by multiple predators, making them a key part of the Jurassic food chain. This steady supply of easy prey may explain why early predators thrived without needing extreme hunting adaptations. The findings offer a rare glimpse into how dinosaur ecosystems truly worked.

Pachycephalosaurus: Beast of the Week

This week we shall be checking out a well-known dinosaur with an iconic skull.  This dinosaur is one of my personal all time favorites.  I will never forget seeing it's awesome representation in The Lost World: Jurassic Park in the movie theater when I was only eight years old.  The way it smashed that truck...it changed me.  Say hello to Pachycephalosaurus wyomingensis!

Anurognathus: Beast of the Week

This week we will be checking out a unique little pterosaur, Anurognathus ammoni!  Anurognathus lived in what is now Germany during the late Jurassic period, about 150 million years ago.  It was tiny, sporting a 14 inch (35.5 cm) wingspan, and would have likely eaten insects.  It's genus name translates to "Frog Jaw" since its skull was similar looking to a frog's, being extremely blunt with a wide mouth.  Watercolor reconstruction of Anurognathus ammoni by Christopher DiPiazza.Anurognathus' sku
