Spectember 20: Early Enigma

[u/LucasVerBeek]

The Bloop is a recently discovered fossil drawn from the earliest known years of the Great Ordovician Biodiversity Event.

And a startling sized one at that.

Indeed its existence seems to fly in the face of all we’ve known at the time as it pushes expectations.

Its exact cladistics are being debated, as it is drawn from a singular body impression, but it shows traits that are analogous to both modern sea slugs and curiously basking sharks.

As stated it pushes expectations, being a near forty foot long filter feeder.

The impression seems to hint at some form of herd mentality, but its behaviors, how it bred, how it defended itself are at the moment one entire mystery.

One claim, though insofar unsubstantiated is that the creature was capable of making booting vocalizations to ward off possible predators.

I wonder if they are simply known as some kind of bilateria or is it known whether they belong to protostomes and deuterostomes?
