proprio giusto su questo argomento ne parlavo con uno degli autori...che scrive così: Joe Moysiuk We based our 'stilt' interpretation in the paper on the shape of the helens, and their angle of preservation relative to the body, as well as the occasional presence of brachiopod epibionts. Still speculative, of course, but I think it fits more of the evidence than other proposed models. If you come up with a better hypothesis, I'd love to hear it
....Joe Moysiuk Gianpaolo - it's a great reconstruction, nice to see the whole environment represented!
:) We considered a 'snowshoe' configuration for Haplophrentis, but if the helens were splayed out on the sediment they would have projected down into the mud because of their curvature. This wouldn't be ideal for structures playing a role in support on soft sediment, and it isn't consistent with our other observations (angles of preservation, presence of epibionts). Of course, we can't rule out other hyolithid species having had somewhat differing helen morphology and function.
mi sono già espresso in privato: dovrebbe diventare un volume a fumetti
...mi ricorda un poco la posizione di un Gorilla...
La ricostruzione è magnifica, adoro lo stile, la posizione dell'organismo (ben che correttamente ripresa da quella pubblicata dal ROM) mi piace meno.
Se viveva su fondo sabbioso/fangoso avrebbe avuto tendenza ad infossarsi nel sedimento, se su substrato roccioso, in caso di correnti, a ribaltarsi.
Ipotesi.
