By stumps the West Indies top-order had built on that dominant bowling effort with a lead of 158 runs with eight wickets in hand
Kemar Roach led the demolition of Bangladesh with a five-wicket haul as the tourists were dismissed for 43, their lowest total ever in Test cricket, before lunch on the opening day of the first Test against the West Indies at the Sir Vivian Richards Stadium in Antigua on Wednesday.
By stumps the West Indies top-order had built on that dominant bowling effort in reaching 201 for two, a lead already of 158 runs with eight wickets in hand.
Opening batsman Kraigg Brathwaite played his usual sheet-anchor role to perfection in compiling an unbeaten 88 from almost five hours at the crease.
He put on 113 for the first wicket with Devon Smith (58), while Kieran Powell stroked his way to 48 in an 81-run stand before falling just before the close of play.
Their serene progress through two sessions contrasted sharply with Bangladesh's woeful batting performance.
Apart from being their lowest Test innings total and lowest for any team in Test cricket in the Caribbean, it was also the second shortest first innings of a Test match -- 18.4 overs - in the game's 141-year history, bettering by just one delivery Australia's dismissal for 60 off 18.3 overs by England at Nottingham in 2015.
Put in to bat on the greenest surface seen in 10 years of Test cricket at the venue, the Bangladeshis were no match for the quality of the West Indies fast bowling led by Roach, who set the rout in motion by claiming the first five wickets for eight runs in the space of 12 deliveries despite appearing to be troubled by a muscular strain behind his right knee.
However it was the visiting batsmen who felt the greatest discomfort with only opener Liton Das getting into double-figures in a performance that once again exposed the vulnerability of their players in conditions away from what they are generally familiar with on the Indian sub-continent.
Das was sixth out for 25, an ugly heave offering a simple catch to Roston Chase at backward point off Miguel Cummins to end any prospect of Roach claiming all ten wickets in the innings.
Cummins, whose place in the final XI was in question after a lack of success in the preceding three-Test series against Sri Lanka, took two more wickets before West Indies captain Jason Holder, fresh from a nine-wicket haul despite defeat in the final Test against the Sri Lankans in Barbados just over a week earlier, polished off the innings with the wickets of Kamrul Islam and debutant Abu Jayed.
Jayed was always in line for his maiden Test cap given the pitch conditions and the absence through injury from the tour of Bangladesh's most effective seamer Mustafizur Rahman.
But he would not have expected to be at the crease as the last man in the batting line-up or being the first to use the new ball in the West Indies reply, all within his very first session of Test cricket.
If they were relying on their most senior players to navigate them through what was expected to be a tough opening session, Bangladesh were poorly served by the experienced quartet as captain Shakib al Hassan, former skipper Musfiqur Rahim and all-rounder Mahmudullah all failed to score while opener Tamim Iqbal contributed four runs before becoming the first wicket to fall, caught by wicketkeeper Shan Dowrich, to trigger the swift tumbling of wickets.
Four days after his 30th birthday, Roach's unerring accuracy and decent pace proved too much for batsmen ill-equipped to cope with the seaming ball.
Four of his five wickets came via catches to the wicketkeeper or the slip cordon while Mushfiqur was trapped LBW, a review of the on-field decision being upheld by the television official.
Bangladesh's bowlers were made to look pedestrian in the conditions and their plight was worsened by chances put down off both Smith and Brathwaite. Yet there was delight on an otherwise forgettable first day of Test cricket for Abu Jayed when he had Smith caught at the wicket to claim his maiden Test success.
Mahmudullah was the other wicket-taker, removing Powell to a deflected slip catch 15 minutes before stumps.
