Tanystropheus longobardicus

Tanystropheus longobardicus

Tanystropheus longobardicus possessed one of the most extreme body plans in vertebrate history, dominated by a stiffened neck exceeding the combined length of its body and tail. Composed of merely 13 hyper-elongated vertebrae bound by rod-like cervical ribs, this remarkable neck was held relatively rigid rather than flexing like a snake. Fossils from the marine deposits of Monte San Giorgio indicate it lived along shallow Tethyan coastlines, ambushing small cephalopods and fish with swift darts of its narrow, toothy head.

Why interaction risk is low
Extinct species known only from fossil remains; completely safe to observe in museum collections.
Responsible observation
  • Museum etiquette: Observe mounted fossil specimens and casts without touching delicate matrix surfaces.
  • Fossil observation: Look closely at the neck vertebrae to spot the slender, needle-like cervical ribs.
