† ˈtubulite Obs.
[ad. mod.L. tubulītēs, introduced by Gesner, Tractat. Physic. de Petrificatis, 1758.]
A fossil or petrifaction of a tube or tubular shell occupied by an animal.
Gesner specified the tubular shell of the ship-worm, a lamellibranch mollusc, the coiled tube of a Serpula, the tubular shell of a Dentalium, all then regarded as ‘worms’. But as these were the shells of different animals, the word was not permanently used.
