Utilisaurs

Dinosaur-derived biomachines engineered by prehistoric or alt-timeline supercivs.

1 - Hadrosaur "sump pump" for draining and clearing canals, chinampas, and other such infrastructural waterways.

2 - The "teacup" version for home use, showing the terminal end of the pump system and the mechanism by which it operates (the bladder on the head inflates and deflates rhythmically via respiration to produce vacuum suction).

3 - Hadrohydra (Hadrocerberus?) with conjoined bills, engineered to scrape and smooth the surface finish of architectural structures. Development of this organism likely involved a minor modification of natural mineral foraging behavior (i.e. tendency to scrape salt-rich clay from cliff faces).

4 - Crane or shovel derived from a "duckbilled" sauropod (i.e. Nigersaurus). Note the inclusion of heron-style "hinged" neck vertebrae:

and the externalization of the hypertrophied muscle cables to reduce forward operational weight.

5 - Tricephalized sauropod adapted into a cliff-face mining machine (likely exploiting a natural salt-mining behavior as per 3 above).

6 - Superheavy variant of 5. Note the duplicate load-bearing limbs.

7 - The tableau from my bathroom counter that inspired 3, 5, and 6.

8 - A heavily modified sauropod repurposed into something like a jackhammer or "steam" roller. High-frequency infrasonic vibrations produced in the thorax (as per pachyderms) are channelled through the foot pads to compact soil and other forms of  loose granular substrate. Variants of this animal are employed in a military capacity clearing minefields and as amphibious "living tanks" negotiating soggy marshlands. Note the hinged "heron neck" vertebrae at midbody, forming an articulated linkage connecting the two independent body sections.

 may be a feral "n^th" generation derived variant of such a biomachine.
